Fiber Optic Interface

FOI-01-221

The Fiber Optic Interface was primarily designed to interface Fiber Optic Switches (FiberSwitch™) to electrical circuits. It provides a safe optical signal that can be sent into hazardous areas, as required by IEC 60079-28. Up to 32 FOI's can be connected in a network over RS485 (Modbus RTU) or Ethernet (Modbus TCP/IP) allowing 64 Fiber Optic Switches (2 switches/FOI) to communicate with a master over the network.


- Equipped with two optical I/O, and two electrical I/O.

- Uses standard multimode fiber optic cable and ST connectors.

- Low power consumption (<2.0W).

- Accepts a wide range of power supply voltages.

- Performs fiber optic loop tests.

- Programmable to suit many applications (OptiLink and OptiNet software included).

- Uses standard Mini Type B USB connector for computer connectivity.

- Networkable over RS485 (Modbus RTU), also provides support for networkable fiber optic switches (FiberSwitch™) over Modbus RTU(RS485), or Modbus TCP/IP(Ethernet).

- Uses high efficient VCSEL diodes for the optical outputs.

- Generates alarm for interface malfunction and power loss.

- Electrical inputs are ESD protected (4kV contact discharge, 8kV air discharge as per IEC 61000-4-2.
