Overview

Overview of 4 Channel 4-20mA Analog Signal to Fiber Optic Convert

Cj-af series products are a type of multi-channel analog signal converter. It adopts the latest ARM chip, which is quite stable, reliable low power, supports 1 ~ 4 channels 4~20mA current analog to Fiber Optic transmission.
It requires no change of the user communication protocol solves the problem of electromagnetic interference, ground ring interference thunder destroys, which greatly improve the signal reliability, safety confidentiality, at the same time solve the problem of traditional mode of short distant transmission.
Protection grade is IP30, strengthen cabinet, 35mmDIN guide installation, industrial stard DC24V power supply, possess the protection function of power polarity reverse connect.
