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.
- Contact closure signal/TTL digital signal interface:
* Independent 1 ~ 4 channel input, 1~4 channel output.
