Analogue input Ethernet modules

16 Channels into an inch-wide unit saves space and costs

Acromag has released two of their newest models in the BusWorks^® XT Series of Ethernet I/O modules. The XT1230 and XT1240 models provide a 16-channel interface for single-ended analogue current or voltage input signals with Ethernet/IP, Modbus/TCP, Profinet, or i2o^® peer-to-peer communication. The space-saving inch-wide design features dual Ethernet ports, removable front-facing terminal blocks, and DIN rail power bus support. Its convenient USB-to-PC connection and free Windows software makes configuration quick and uncomplicated. Suitable for use in harsh environments, all modules operate from -40 to 70°C with noise immunity, surge protection, and CE compliance. UL/cUL Class 1 Division 2 Zone 2 hazardous location approval is pending.

“We are continually expanding the BusWorks XT Series in order to provide more modules with even greater versatility,” explained Acromag sales manager Rob Frewald. “Beyond our digital offerings, we now support up to 16 channels of analog input for our customers to squeeze in more channels at a lower cost, even when space is scarce.”

The XT1230 accepts current inputs of 0-11mA, 0-20mA, 4-20mA, ±20mA, or 0-20 amps AC with optional toroid sensor. The XT1240 accommodates ±5V, ±10V, 0-5V, or 0-10V input ranges. All units run off a 12-32V DC power source (2.8W) at the terminals or through an integrated power connector bussed along the DIN rail that can provide primary or redundant power. Each model offers a choice of Ethernet/IP, Profinet, or Modbus TCP/IP protocols with peer-to-peer i2o communication support. Dual 10/100 Ethernet ports allow daisy-chaining units together to simplify cabling and minimize the network switches required, reducing overall system costs.

For even more dependable communication, BusWorks XT units employ Innovasic PriorityChannel technology which makes certain that critical data is received on time regardless of traffic on the network. PriorityChannel provides determinism at the device for consistent transmission of time-sensitive data with any of the Ethernet protocols.

Many other features add greater flexibility and performance. High input impedance reduces loading on voltage loops with XT1240 models, with the XT1230 models’ low input impedance reduces loading on current loops. The configuration software enables use of sample averaging on a per-channel basis. For reliability, operation and diagnostic LEDs offer visual status updates and aid in trouble-shooting.
