Overview

Overview of Multi-Channel Dry Contact Signal to Fiber Optic Converter

Cj-KF Series products are a type of multi-channel contact closure fiber conversion equipment. It adopts the latest ARM chip, which is quite stable, reliable low power, supports 1 ~ 4 channels contact closure(Dry Contact or CC) signal 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.
