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.
