NT2620 Series RTD/resistance module

Aug. 19, 2022

Acromag added to the Busworks NT Series of expandable remote Ethernet I/O modules with the NT2620 Series RTD/resistance module. 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 webserver with Modbus TCP/IP or EtherNet/IP communication to monitor or control the internal I/O channels.

The Modbus TCP/IP or EtherNet/IP communication is field-selectable saving costs of additional modules. An integrated DIN rail bus allows a connection of as many as three NTX expansion I/O modules. The space-saving design requires only 25mm of DIN rail per module. Ethernet I/O modules distribute 9-32V DC 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 ideal for use in harsh environments.

Profinet communication is planned for release soon. 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. Multicast capability is included.
