Ethernet Remote I/O Modules

Acromag’s Busworks NT2000 Series is an Expandable Ethernet Remote I/O Modules Solution.

There are two model types:  NTE Ethernet Models & NTX Expansion Models

Firstly, NTE handle the network communication and interface up to 16 analog or digital I/O channels for remote monitoring or Control applications.

Whereas the NTX expansion models provide a cost effective way to add a mix of I/O signal types under a single IP address.

NTE provide Multi-protocol support

NTE Ethernet I/O modules are pre-programmed to support Modbus/TCP, Ethernet/IP and Profinet* protocols.  Select which is to be used.  They also support direct i20® peer-to-peer communication without a master.

Features include:

  • Integrated I/O expansion bus
  • Up to 64 I/O channels per port (this incorporates 3 x NTX Expansion Models)
  • Anlaog, Digital and Temperature I/O mix on one port
  • I20 peer-to-peer or multi cast communications
  • Rugged Design, -40° to 70°C
  • Hazardous location approvals

Ethernet-based Configuration with easy setup from any web browser

The NTE modules have a built in webserver.  Firstly, this provides convenient configuration without installing software. Web pages lead you through the options to set IP addresses, protocol and I/O parameters.  The diagnostics page enables you to monitor I/O values directly from your PC, tablet or smartphone.

There are advanced features for IIoT and local control logic functions.  Such as peer-to-peer communication, conditional logic computation and alarm output.
