BusWorks NT series remote I/O modules

July 6, 2022

Acromag’s new BusWorks NT series remote I/O modules are now enhanced with EtherNet/IP support. Applications for these high-performance Ethernet I/O modules are remote monitoring and control, condition monitoring and predictive maintenance, building HVAC energy consumption, and more. These modules were tested at an ODVA and received an ODVA Declaration of Conformity. 

NTE Ethernet I/O models have dual RJ45 ports and a webserver with Modbus TCP/IP and Ethernet/IP communication to monitor or control the internal I/O channels. An integrated DIN rail bus allows connections of as many as three NTX expansion I/O modules. Each I/O module adds as many as 16 input or output signals allowing a mix of control signals networked on one IP address. Ethernet I/O modules distribute 9-32V DC power along the DIN rail bus to expansion modules. 

The NT2000 Series offers a broad variety of I/O signal processing options. Nine I/O configurations are available as either NTE Ethernet I/O or NTX expansion I/O models. Analog I/O models feature eight differential or sixteen single-ended inputs for monitoring current or voltage signals. Discrete I/O models provide 16 tandem input/output channels with either active high/low input and sinking/sourcing output. A six-channel mechanical relay output model is also available. More models will release over the coming months for additional I/O functions.

Profinet communication is planned for release soon. Each module will support all three protocols which are selectable using any 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. Multicast capability is included.
