AI 622

This module reads 8 current analog signals. The inputs are isolated from the backplane bus. LED and optical isolation barrier.

AI 621

This module supports the 8 Thermocouples, 8 × ۲-wire RTDs, 8 × ۳-wire RTDs or 8 × ۴-wire RTDs that all inputs are isolated from the backplane bus.

 

Module Specifications

Supported Sensor Types:

  • Thermocouples: Types B, E, J, K, N, R, S, T
  • RTDs: PT100, PT500, PT1000

 

Cold Junction Compensation (CJC) Options:

For thermocouple inputs, cold junction compensation can be configured in module settings using one of the following reference methods:

  • Internal: Module temperature sensor
  • External: Sensor connected to Channel 1
  • Fixed Reference Temperature; 25°C (77°F) or 0°C (32°F)

Ao 672

This module provides 8 loop-powered current outputs. Each output can be individually configured to a 4-20mA range. Every output channel consists of current-limiting components, EMC protection components, an input state indication LED, and an optical isolation barrier.

AI 627

The AI627 is a three-phase power metering module for measuring electrical parameters such as voltage, current, power factor, active/reactive/apparent power, and frequency of electrical lines. The device communicates with MRT RTUs such as the RTU451/450B via backplane bus, and multiple devices are supported by a single RTU.
