Acromag BusWorks NT Expandable Remote-I/O Modules For Ethernet

Distributed networking I/O modules NTE and expansion I/O modules NTX

The Acromag BusWorks NT series are industrial DAQ and control modules and expansion I/O modules for a high-density, cost-efficient remote I/O solutions. The NTE Ethernet models are the base units that handle network communication and interface up to 16 analog or digital I/O channels for remote DAQ, monitoring, or controls. They are pre-configures to support Modbus/TCP, Ethernet/IP* and Profinet* protocols - just select which is to be used. The modules also support direct "i2o" peer-to-peer communication without a master. The NTX models are expansion modules that add a mix of I/O channels under a single IP address in a very cost-effective way.

  • Analog and digital remote-I/O modules.
  • Up to 64 I/O channels per port.
  • Mix analog, digital, and temperature I/O on one port.
  • Multi-protocol support: Modbus/TCP, Ethernet/IP* and Profinet*.
  • IIoT*/multicast or peer-to-peer communication.
  • Integrated I/O expansion bus - expand locally: Link up to three NTX expansion I/O-modules to an NTE Ethernet base I/O-module over the integrated DIN rail I/O-bus connectors.
  • ...or daisy-chain remotely: Connect NTE Ethernet I/O-modules over up to 10 m with a daisy-chain topology using the internal dual-port switch to simplify network cabling.
  • Easy setup from anywhere with any web-browser: Built-in web-server in NTE Ethernet I/O-modules for convenient configuration without installing any software. Set 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: Quickly setup advanced capabilities such as: Peer-to-peer communication, counter/timers, if/then/else logic*, alarm output*, RESTful APIs*, OPC-UA server*, MQTT support*, field-upgradeable.
  • Rugged design, -40...70°C, hazardous location approvals.
