Description：
The switch fiber modem provide 2channel switch and 1channel serial data(RS232/422/485) over fiber tansmission. The fiber modem also can provide only 4 one-way switch over fiber transmission.

The product solve the electromagnetic interference, ground loop interference and lightning damage problems, improve the reliability, security and confidentiality of the data communication. The switch fiber modem can be widely used in various industrial control, process control, and traffic control and other occasions, especially for banking, electricity and departments have special requirements for electromagnetic interference environment and systems.

Features：

Based on the integrated circuit intellectual property rights;

The input switch normally open and close automatically, when the input state, switch output that is why state, convenient opening;

The switch quantity of other switch state stability in the boot state or fiber no access, no chaos motion state;

Provide 1 way switch and RS485 data;

A switch interface lightning reaches IEC61000-4-5 (8/20 μ S) differential mode: 6KV, impedance (2); common mode: 6KV, impedance (2) standard;

The optional AC 220V, DC -48V, DC +24V, DC power supply positive and negative pole points (this device supports only DC +5V supply).
