Acromag BusWorks NT Series remote Ethernet I/O modules

Acromag’s BusWorks NT Series remote I/O modules are now enhanced with EtherNet/IP support. EtherNet/IP is traditional Ethernet combined with an industrial application layer protocol targeted to industrial automation. Applications for the high-performance Ethernet I/O modules are remote monitoring and control, condition monitoring and predictive maintenance, building HVAC energy consumption, and more.

The 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 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.

Ethernet I/O modules distribute 9–32 VDC power along the DIN rail bus to expansion modules. The space-saving design requires only 25 mm of DIN rail per module. Hazardous location approvals, high noise immunity and -40 to 70°C operation make the I/O suitable for use in harsh environments.

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 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.

The Ethernet I/O modules are user-configurable for Ethernet/IP or Modbus/TCP, offering a convenient solution for engineers with multiprotocol control systems. 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.
