Acromag Busworks NT2620 RTD/resistance Ethernet I/O module

Acromag’s latest addition to the Busworks NT Series of expandable remote Ethernet I/O modules is the NT2620 Series RTD/resistance module. Designed to be a cost-effective modular solution, it supports four RTD/resistance inputs and two bidirectional discrete digital I/O channels to monitor temperature limits with conditional logic.

NTE Ethernet I/O models have dual RJ45 ports and a web server with Modbus TCP or EtherNet/IP communication to monitor or control the internal I/O channels.

The Modbus TCP or EtherNet/IP communication is field selectable, saving the cost of additional modules. An integrated DIN rail bus allows connection of up to three NTX expansion I/O modules. The space-saving design requires only 25 mm of DIN rail per module. Ethernet I/O modules distribute 9–32 VDC power along the DIN rail bus to expansion modules.

Hazardous location approvals, high noise immunity and -40 to 70°C operation make this I/O suitable for use in harsh environments. Profinet communication is planned for release soon.

Protocol support is selectable using a web browser to configure the network settings and I/O operation. The modules typically function as a network slave, but also offer Acromag’s i2o peer-to-peer communication technology to transfer data between modules directly without a host or master in between.
