Isolators / Distributors

I. Overview

A. Main functions and features

● Fully digital adjustment

● The input, output and power supply are magnetically isolated from one another

● Converts DC input signals into isolated standard process signals

● With power indicator lamp

● Card-mount signal isolation processor
