Cj-mf61 series anolog/digital signal fiber optic converters
Products description:

Cj-mf series products are 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 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 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.
