Ao 672
This module provides 8 loop power current outputs. Each output can be individually configured on range 4-20mA. Every input channel consists of current limiting components, EMC protection components, input state indication LED and optical isolation barrier.
AI 627
AI627 is 3 phase power metering module for measuring electrical parameters such as Voltage, Current, Power Factor, Active/Reactive/Apparent Power and Frequency of electrical lines. Device communicates with MRT RTUs such as RTU451/450B via backplane bus and multiple devices are supported via single RTU.
