comark 1~4chs Analog&digital Fiber Optical rs232 multiplexer cj-mf61-m
Product Detailed
Multiplexer 1. 1~2chs RS232/485/422 multiplex 2. up to10chs optional 3. One fiber port,DIN35,DC24V power


P/N: Cj-mf61-m

Analog signal digital signal fiber multiplexer, 1 ~ 4 chs analog signal, 1 ~ 4 chs digital signal, 1 ~ 2 chs RS232/485 multiplexing, Multi-mode, 0~15Km, ST/SC/FC (optional).



Cj-mf 61 series products are a type of multi-channel analog signal, the digital signal, serial ports RS232/485/422 fiber conversion multiplexing equipment. It adopts the latest ARM chip, which is quite stable, reliable low power, supports 1 ~ 4 channels the digital TTL signal/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 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.


 Features:Contact closure signal/TTL digital signal interface:
