Overview of Analog/Digita and Serial RS232/485/422 to Fiber Optic Converter

This series converter is a type of multi-channel analog signal, the digital signal, and serial ports RS232/485/422 fiber conversion multiplexing equipment. It adopts the latest ARM chip, which is quite stable, reliable and low power, supports 1 ~ 4 channels the contact closure signal, 1 ~ 4 channel analog (voltage/current), 1 ~ 2 channel RS232/485 or a channel RS422 signal in the fiber alone or multiplexing transmission. It requires no change of the user communication protocol and solves the problem of electromagnetic interference, ground ring interference and thunder destroys, which greatly improve the signal reliability, safety and 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 standard DC24V power supply, possess the protection function of power polarity reverse connect.
