Ethernet Expandable Remote I/O: BusWorks NT Video

New BusWorks® NT series remote Ethernet I/O modules interface 16 analog or discrete I/O channels and feature an I/O expansion bus linking up to three additional I/O modules!

AcroMaggie gives a brief overview of Acromag’s BusWorks NT Ethernet expandable remote I/O modules in the video below. 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.

Ethernet Expandable Remote I/O Offers Variety of I/O Signal Processing Options

The NT 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. Discrete I/O models provide 16 tandem input/output channels with either active high/low input and sinking/sourcing output. Analog I/O models feature either eight differential or sixteen single-ended inputs for monitoring current or voltage signals. 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.

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; as a result, it can transfer data between modules directly without a host or master in between. Multicast capability is also included.

Rugged, Space-saving Design

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. Additionally, hazardous location approvals, high noise immunity, and -40 to 70°C operation make this I/O ideal for use in harsh environments.
