Acromag BusWorks XT1210 and XT1220 ethernet modules

Acromag’s BusWorks XT series of ethernet I/O modules now includes the XT1210 and XT1220 models, providing an 8-channel interface for analog voltage or current input signals and EtherNet/IP, Modbus/TCP, Profinet or peer-to-peer communication.

Differential inputs have good noise rejection for reliable measurements when radiofrequency or electromagnetic interference is present. Internal software helps eliminate the effects of network traffic loads for more reliable messaging.

The design features dual ethernet ports, removable front-facing terminal blocks and DIN rail power bus support. Its USB-to-PC connection makes configuration fast and simple with Windows software. Suitable for use in harsh environments, all modules operate from -40 to 70°C with high voltage isolation, surge protection and CE approval.

The 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. The use of differential inputs and PriorityChannel is said to eliminate the risks of signal interference and network congestion.

The XT1210 model accepts current inputs of 0-20 mA, 4-20 mA, ±20 mA DC, or 0-20 A AC with an optional toroid sensor. The XT1220 accommodates ±5 V, ±10 V, 0-5 V or 0-10 V DC input ranges. All units run off a 12- 32 V DC power source (2.8 W) at the terminals or through an integrated power connector bussed along the DIN rail that can provide primary or redundant power.

Dual 10/100 ethernet ports allow daisy-chaining units together to simplify cabling and minimise the network switches required. High input impedance reduces loading on voltage loops. The configuration software enables use of sample averaging on a per-channel basis. Operation and diagnostic LEDs offer visual status updates and aid in troubleshooting.
