Acromag BusWorks NT2000 series remote Ethernet I/O modules

Acromag’s BusWorks NT2000 series remote Ethernet I/O modules provide an Ethernet interface for analog, discrete and temperature signals. NTE Ethernet I/O models have dual RJ45 ports and a web server with Modbus TCP/IP communication to monitor or control the internal I/O channels.

An integrated DIN rail bus allows connection of up to three NTX expansion I/O modules. Each I/O module adds up to 16 input or output signals allowing a mix of voltage, current, temperature, TTL and relay control signals networked on one IP address.

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 the I/O suitable for use in harsh environments.

The 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 16 single-ended inputs, for monitoring current or voltage signals.

Discrete I/O models provide 16 tandem input/output channels with active high/low input and sinking/sourcing output. A six-channel mechanical relay output model is also available. For temperature monitoring, a thermocouple input model supports many sensor types and also millivolt ranges.

Currently, the NTE I/O modules support only Modbus TCP/IP communication, but will soon include Ethernet/IP and Profinet protocols. Each module will support all three protocols, 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, transferring data between modules directly without a host or master in between. Multicast capability is also included.
