IS Temperature transmitter.

A new member of the Moore Industries Associated Intrinsically-Safe (AIS) family of products has been announced with the release of the THZ3 compact Dual Input Smart HART® Temperature Transmitter in DIN Rail Mount housing with Associated IS sensor connections. The intrinsically-safe -AIS option allows direct connection of sensors located in hazardous areas since it includes an internal intrinsically-safe barrier in the front end of the THZ3. The Universal mounting bracket easily snaps on and off of 35mm Top Hat DIN-rails and standard relay tracks.

The THZ3-DIN with the -AIS option is an associated apparatus suitable for mounting in Non-Hazardous or Class I, Division 2/Zone 2 hazardous locations with sensor input terminals connected to equipment or sensors located in Class I, II, III, Division 1/Zone 0/1 hazardous locations. Installation costs are reduced if an associated apparatus like the THZ3-DIN with -AIS option is used, since the intrinsically-safe barrier is embedded in the receiving device. There is no need for the additional cost of the IS barrier, cabinet space, high integrity clean ground connection, separate power supply, or custom vendor backplanes. This drastically reduces the cost of purchasing, installation, and maintenance versus more traditional approaches requiring a separate Zener or isolating barrier. Blue connectors on the THZ3-DIN with -AIS option provide a visual way to recognize the Associated IS capability.

The dual-input THZ3-DIN with the -AIS option offers all the features customers have come to expect from Moore Industries temperature transmitters like reliability and accuracy, HART 7 compliance, 20 bit resolution, sensor failover and backup capability, device intelligence including Sensor Drift and Corrosion Detection, and Input Simulation capability. The THZ3 is also HART and DTM Programmable for fast and accurate setup with a user-oriented basic configuration. The THZ3 is HART configurable via any HART handheld configurator or HART compatible host. Users can also program or monitor with any FDT compliant host or program, such as PACTware, utilising their DTM.
