Safe dissipation of stray currents

The new Harting Han® HC Modular 250 PE is a high-current contact designed to provide safe dissipation of stray currents in applications where the protection function is implemented with pluggable PE (protective earth) conductors.

The new contact has a compact and robust design, and is designed to be used instead of a power contact in the Han® HC Modular 250 mounting frame. The flexible configuration and arrangement make coding possible. A commercially available screwdriver is all that is needed for assembly and dismantling.

The new contact is vibration-proof, and offers low contact resistances between hood and housing. It supports crimping in accordance with DIN EN 46235, and is compatible with Harting's existing HC 250 holding frame.

The Han-Modular® series is a highly versatile, open connector system that allows users to configure connectors to match the needs of particular applications. The new Han® HC Modular 250 PE supplements more than 30 existing modules for handling electrical, optical and pneumatic signals.

Modular safety system for safety-related applications expanded by AS-i

The Siemens Industry Automation Division has expanded its Sirius 3RK3 modular safety system by a new central module with AS-i (AS-Interface).

Sirius 3RK3 Advanced can be used as an AS-i safety monitor, and thus expands standard AS-i networks for safety-related applications. Typical applications include the collection of sensor signals in widely spaced plants, slave-to-slave communication in modular machine concepts, safety-related communication with plant components, or distributed switching-off of drives via the AS-Interface.

The new module is suitable for standard and safety-related signals on the AS-i bus, and has 12 independent AS-i enabling circuits. The quantity structure and functionality of the Sirius 3RK3 Advanced have been greatly increased compared to the Basic version. For example, nine expansion modules can now be connected instead of seven, and expanded cyclic data exchange is possible over Profibus. The functionality of the MSS ES engineering software has also been expanded. It is now possible to download the parameter settings and carry out online diagnostics of the unit over Profibus.

The macro function is also new with which function units can be combined in a library. The macros can be exported and imported, and thus reused in other projects.

New data portal goes live!

Maximum speed and easy searching and finding are the main advantages of the new EPLAN Data Portal which already includes data for more than 120,000 devices. Users benefit from access to the latest, up-to-date data which can be more quickly and easily integrated in engineering using the new EPLAN Platform 2.0.

In addition to numerous new and expanded functions, Version 2.0 of EPLAN Data Portal provides many new component data from manufacturers like Festo, ABB, Phoenix Contact, Endress+Hauser etc.
Following the launch of the EPLAN Platform 2.0, the new EPLAN Data Portal 2.0 has now gone live. Users are enjoying new time-saving functions in the online portal that make it easier to select and use device data and components. The integration of much more manufacturer and device data promises significant practical benefits. A new portal member is Leuze Electronic, manufacturer of optoelectronic sensors who has integrated EPLAN macros of selected switchgears as well as many safety oriented sensors. In time for Version 2.0, Festo has also provided a selection of pneumatic components.

More manufacturers – more data

Mitsubishi Electric has joined the list of new manufacturers with data for PLCs and converters and Dehn + Söhne expanded the offering in lightening and surge protection. But that's not all: ABB has updated its data and Phoenix Contact has adjusted its already extensive range of products. At the SPS/IPC/DRIVES trade fair, Blomberger will present the next update, so that their device data will also support the latest EPLAN Electric P8 2.0 functionality. Future exciting perspectives: the planned integration of Endress+Hauser, which will be announced in Nuremberg.

Function by function
Valuable manufacturer data aside, users can look forward to many new portal functions. One of the eagerly awaited highlights is the "unique ID" which clearly identifies an article in the EPLAN Data Portal. This ID allows data from the portal to be updated even if the local part number is changed. And if the manufacturer so desires, the device data can now be displayed and filtered according to regional availability. Users can quickly and easily select the data relevant to their target market and concentrate on the relevant components. The optimized user interface is also a decisive factor. For example, it now has filter options that can be hidden which significantly speeds up page loading times.

Faster searching, easier finding
Data transparency has been improved by now displaying the number of articles per product group including all subgroups in the manufacturer catalog. This makes it easy to select from many extensive catalogs – time-consuming page-turning is a thing of the past. Another highlight is the new accessory lists for users who used the optimized accessory management in Versions 2.0 of the data portal. Other new features: automatic download of function template macros, referenced parts that are already complete for the mounting layout, and the life cycle status of previous and subsequent parts so that data is always up-to-date.

Fast, easy, convenient: configurator technology
Next step to improve availability and usage of CAE component data is the integration of supplier specific component configurators into the EPLAN Data Portal. Currently Rockwell, Endress + Hauser and EPLAN are running a common project to create a seamless interface between E&H product configurator and EPLAN Data Portal. The engineer is able to configure the needed E&H devices guided by the configurator and then drag & drop the detailed CAE data directly into his electrical project documentation – simply genius high end engineering. The integration of Rittal Therm is another technological milestone. All necessary components, assemblies and accessory parts are simply configured and then mounted in the 3D mounting layout of the enclosure.

Industrial Defender HIPS is whitelisting-based technology which enforces a limited "whitelist" of approved applications on each host system. By allowing only approved applications to execute, HIPS blocks all unauthorized applications. HIPS goes beyond "blacklist" technology by protecting against unknown and sophisticated attacks (e.g., rootkits, memory exploits and zero-day threats)

ATEX approved LBFS level switch

No additional Zener barrier required thanks to ready-for-use isolation module PROFSI3 LS

Baumer’s multi-purpose LBFS level switch is now available in three different ATEX configurations which enable safe level detection in explosive gaseous and dusty atmospheres, typically found in the chemical, pharmaceutical, or food industries. Baumer uses a highly specialised protective design for the ATEX versions of the LBFS. Thanks to this, versions Ex ta for dust (zones 20, 21, and 22) and Ex nA for gas (zone 2) can be used without a Zener barrier because the housing itself already provides all the necessary protection. This is very cost-effective because usually all sensors for hazardous areas require a Zener barrier. The ATEX certifications cover zones 0, 1, and 2 (gas) as well as zones 20, 21, and 22 (dust). Quick installation and ease of use is also ensured for version Ex ia for gas (zones 0 and 1). For this version, Baumer provides the ready-for-use isolation module PROFSI3 LS which is specially designed for use with Baumer’s level switches LBFS and LFFS. This dedicated isolation module saves users the time and effort of selecting and configuring an additional Zener barrier to operate the sensor.

The PROFSI3 LS can operate with DC voltages from 22 VDC to 120 VDC as well as AC voltages from 90 VAC to 253 VAC. The LBFS is based on the frequency-sweep technology, a method particularly suitable for precisely measuring the level of solids and powders. As the processing of such materials often creates explosive dust, the new ATEX versions open a wide range of new applications particularly valuable for typical LBFS users in the chemical and pharmaceutical industries.

But industries like oil and gas, energy production, and milling will also find this new level switch convenient. The ATEX versions of the LBFS level switch can easily be adapted to the needs of very diverse applications thanks to a wide range of available process connections including G½”, G3/4”, G1”, G½” hygienic, G½” for reverse assembly, M18x1, and G3/4 NPT. More connections are available upon request.

The intrinsically safe PROFSI3 LS interface shields the safe area from the hazardous area through galvanic isolation. The level detected within the hazardous area is transmitted to the safe area through a single-pole double-throw relay.

Wireless user requirements for factory automation

The ISA100 committee has completed a new technical report that presents user and market-related requirements for the design, operation and maintenance of wireless systems throughout their life cycles in factory automation. Factory automation applications involve specific technology, control and information systems that are characterized by discrete operations with possible extensions into batch process control. Examples include automotive manufacturing, packaging machinery, machining and robotics.

ISA-TR100.00.03-2011, “Wireless User Requirements for Factory Automation,” provides use case descriptions and comparisons, descriptions of factory automation topologies, and recommendations for attributes and values for existing, emerging and conceptual solutions for wireless communications as applied to factory automation applications.

The technical report was development by ISA100 Working Group 16 on Factory Automation, which has focused on wireless technology and system architectures for the link between sensors/actuators and automation systems. While wired links between conventional sensors and actuators can often be used, many repetitive motion applications such as machine tools and robotics make wire replacement a major source of work flow interruption and high maintenance cost—driving the desire to find ways to replace wiring with fast, low-cost wireless connections.

The ISA100 standards committee is developing a family of standards for wireless communications in industrial automation applications. The new technical report represents the extension of ISA100 to the factory automation sector, notes Cliff Whitehead of Rockwell Automation, who coordinated the collaborative development of the document. “We plan to further extend this reach with an industry forum on Wireless in Factory Automation in the March-April timeframe of 2012,” he stated.

Solid state switches save space with 17.5mm width

World’s first 17.5mm solid state relay and contactor for DIN rail and panel mounting offer enhanced electrical and mechanical performance in the same form factor as miniature circuit breakers

Carlo Gavazzi has consolidated its range of solid-state relays and contactors, introducing the first such devices to be available in 17.5mm width. Space-saving RG series switches ensure reliable operation and excellent longevity, offering transient voltage protection, robust construction, excellent vibration resistance and advanced features for heat-sink mounting.

The RG series has been introduced to provide cost-effective replacements for existing relays and contactors, keeping part numbers of solid state relays to a minimum in the inventory. As well as rationalising the portfolio, it offers customers major upgrades of both electrical and mechanical performance.

There are two families within the RG series: 17.5mm-wide RGS devices rated up to 600V/90A AC; and RGC, with integrated heat sinks, rated 20A in 17.5mm, up to 30A in 22.5mm housings. RGS switches provide a maximum I²t of 6600A²s, and the RGC’s nominal ratings at 40°C with surrounding temperature de-rated from 0°C up to 80°C.

RG series devices are available for control with DC voltages 4-32VDC. AC controlled types operate with voltages range 20-275VAC and 20-190VDC thus covering standard levels of AC and DC voltages including 24VAC/DC and 110VDC. Switching is selectable between zero-cross or instant-on methods.

Breakdown voltages of 800Vp, 1200Vp or 1600Vp enable RG series switches to cater for the most demanding requirements. Voltage transient protection is provided as standard across outputs using a resistor and capacitor network combined with metal oxide varistors, optionally using transient suppressor diodes where these are more suitable than varistors. There is also protection against control voltage transients; using metal oxide varistors in the case of AC controlled types. DC controlled devices are polarity protected up to 32V DC.

In addition, the RG series offer a radical improvement in mechanical performance. Their design caters for vibration up to 5g (according to IEC60068-2-6), which ensures consistent functionality across a wide range of industries. Key beneficiaries include HVAC, food and beverage and plastics – and even locomotive applications.

RGS solid state relays can be mounted on any heat-sinking surface, conveniently providing a distance between heat-sink mounting holes identical to that of standard hockey puck SSRs. Special stress-relief mechanisms cater for excess forces experienced during heat-sink mounting, as well as when fixing cables to the SSR terminals.

The RG series devices carry CE marks recognising conformity to IEC / EN 60947-4-3, IEC / EN 60947-4-2 and compliance with IEC / EN 62314. RGC types are UL and cUL listed, whilst RGS are UL recognized with pending CSA approval.

T&M connectors

Standard and custom plugs, sockets, probes and test leads

Cliff Electronics manufacture a wide range of 2mm and 4mm plugs, sockets, probes and crocodile clips for professional and industrial test and measurement purposes. They are also a major supplier of test lead sets. These are made to order semi-custom products which combine components from their standard product range with a suitable double insulated cable, standard cable ratings are 1KV (PVC), 5KV and 12KV (silicone).

“Cliff’s test and measurement connectors are already designed into many major international brands of measurement instrumentation and Cliff is also a major manufacturer of custom test lead-sets for blue-chip test equipment OEMs.” Commented John Hall, General Manager of Cliff Electronics

Cliff Electronics test and measurement connector range includes low and high voltage products conforming to the latest EN601010 regulations. These include a range of 2mm and 4mm plugs with matching chassis and right-angle mounting sockets, a comprehensive range of touch-proof sockets and a range of 4mm test probes which also conform to EN601010. Cliff’s chassis sockets are made from high grade engineering plastics with metal parts precision machined and nickel, silver or gold plated depending on the model. 4mm versions have a variety of tag options and the most professional models are insert moulded.

They manufacture a large range of instrumentation crocodile clips, including a “bed-of nails” type used in telecommunications testing. Other crocodile clips available include a basic rating 600V CAT III (1000V CAT II) type available in black, red, blue, green, yellow and green/yellow with a 4mm socket at the rear which accepts a shrouded plug or un-shrouded probe. A miniature version is available for applications where access is restricted and an all metal un-insulated version with curved jaws which give a good grip on bus-bars for earth testing requirements. PVC boots in various colours are available for all Cliff crocodile clips.

A very popular service offered by Cliff Electronics is the design and manufacture of OEM test lead sets to accompany test equipment and meters similar proprietary instrumentation. Manufactured in their factories in Britain and China, custom leads and assemblies can combine standard power plugs with test leads, custom made instrument plugs, and other customised connectors. They can insert moulded cables into special configurations and proof test up to 20KV. 100% testing is available on request as many test leads are safety critical parts.

Active signal conditioner

Available through P J Boner & Co
The SEM1600T from Status Instruments accepts resistance or mV signals from RTD, Slidewire or Thermocouple sensors. The flexible design can accommodate Pt100, 500, 1000, Ni or Cu sensors, slide wire sensors up to 100 K Ohm and 13 different thermocouple types. Other sensor characteristics or your own 22 point linearisation characteristic (for slidewire, linear resistance or mV) can be downloaded into the product enabling you to adapt it exactly to your application.

The output stage offers either voltage, bipolar voltage or current re-transmission signals. The retransmission signal can be ranged to a scale anywhere within the input process range. A transmitter power supply is provided on the output meaning the product can accept sink or source mA applications. The voltage output will drive 2 mA into 5 KOhm @ 10 V.

For ease of use, a high efficiency switch mode power supply is fitted as standard and does not require any adjustment between ac or dc applications. Operating voltages are (10 to 48) V dc and (10 to 32) V ac.

The unit will be available from early September.

This and all Status Instruments are available in Ireland through P J Boner & Co.

Dedicated analyser for H2S in crude oil

Applied Analytics (AAI) has released a second revision of the OMA-300 H2S Analyzer Crude Oil Edition. This product is a specialised configuration of the OMA-300 H2S system equipped with a headspace sample conditioning system. This sampling technique is used to monitor an opaque liquid process; when a sample is too dark or dirty to transmit a light signal, the headspace system produces a representative vapor-phase sample that can be easily monitored via ultraviolet-visible absorbance spectroscopy and correlated to the chemical composition of the liquid process.

“Measuring hydrogen sulfide in crude has become one of our hottest applications,”
says Dan Murphy, senior mechanical engineer. “AAI has always offered a highly effective solution for measuring hydrogen sulfide in opaque liquids, but the current demand for crude analysis has given us cause to rethink our offering. The process resulted in modifications to the Crude Oil Edition of the OMA-300 H2S. The refined design puts everything in one enclosure and adds the capability to monitor multiple crude streams at once using multiple headspace columns running in parallel.”
