The new BusWorks NT Series remote I/O modules from Acromag (Wixom, MI) provide an Ethernet interface for analog, discrete and temperature signals.
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. For temperature monitoring, a thermocouple input model supports many sensor types and also millivolt ranges. More models will release over the coming months for additional I/O functions.
Per Acromag, 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 which is 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.
The NTE Ethernet I/O models have dual RJ45 ports and a webserver 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 product's space-saving design requires only 25mm of DIN rail per module. The 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.
“This Ethernet I/O Solution offers great flexibility to start small at a remote location with a single inch-wide I/O module then inexpensively add more and/or different I/O channels later on the same network port,” comments Robert Greenfield, Acromag’s business development manager.
Acromag has been developing and manufacturing measurement and control products for more than 60 years, and offers a complete line of industrial I/O products including process instruments, signal conditioning equipment, data acquisition boards, distributed I/O systems, and communication devices.
