Wireless Remote Thermocouple Millivolt Input IO Modules NTW2610

The Acromag NTW2610 wireless remote thermocouple millivolt input IO Modules provide a reliable solution for monitoring temperature and low-level sensor signals across PLC and SCADA systems using secure industrial Wi-Fi Ethernet connectivity.

With eight differential thermocouple or millivolt input channels and two additional discrete I/O channels, the NTW2610 enables accurate distributed monitoring of tanks, pipes, heaters, motors, chillers, and industrial processes without installing new network cabling between control cabinets and network infrastructure.

The Acromag NTW2610 is a wireless remote thermocouple millivolt input IO Modules with 2 discrete I/O.  This enables acquisition of temperature and low-level sensor signals across distributed monitoring environments using industrial Wi-Fi Ethernet connectivity.

Each module provides:

  • eight differential thermocouple inputs
  • support for millivolt sensor signals
  • two bidirectional discrete I/O channels

allowing monitoring of temperature instrumentation and control status signals within a single compact remote I/O node.

Supported thermocouple types include:

  • J
  • K
  • T
  • R
  • S
  • B
  • E
  • N
  • with additional support for ±100 mV and ±500 mV millivolt input ranges for low-level instrumentation signals.

    As part of the Acromag BusWorks NT modular remote I/O platform, the NTW2610 supports expansion using NTX modules.  Allowing you to scale systems to up to 64 mixed signal I/O channels under one IP address.  Therefore, simplifying distributed monitoring deployments across industrial infrastructure environments.
