Expandable Remote I/O

Acromag’s Busworks® NT Series lets you add expansion I/O modules for a high-density, cost-efficient remote I/O solution

Base unit NTE Ethernet models handle the network communication and interface up to 16 analog or digital I/O channels for remote monitoring or control applications. NTX Expansion models provide a cost-effective way to add a mix of I/O signal types under a single IP address.

Multi-protocol support

The NTE Ethernet I/O modules are pre-programmed to support Modbus/TCP, Ethernet/IP* and Profinet* protocols. Just select which is to be used. Modules also support direct i2o® peer-to-peer communication without a master.

  • Integrated I/O expansion bus
  • Up to 64 I/O channels per port
  • Mix analog, digital, and temperature I/O on one port
  • i2o peer-to-peer or multicast communications
  • Rugged design, -40 to 70°C
  • Hazardous location approvals

Ethernet-based Configuration

Easy setup from anywhere with a web browser

NTE Ethernet I/O modules have a built-in web server for convenient configuration without installing any software. Several web pages lead you through the options to set your IP addresses, protocol, and I/O parameters. A diagnostics page lets you monitor I/O values from your PC, tablet, or smartphone.

Advanced features for IIoT and local control logic functions

The configuration pages will help you quickly setup advanced capabilities such as peer-to-peer communication, conditional logic computation, and alarm output.

  • Peer-to-peer communication
  • Counter/timers
  • IF/THEN/ELSE logic*
  • Alarm output*
  • RESTful APIs*
  • OPC-UA server*
  • MQTT support*
  • Field-upgradeable
