Contact Closure

For single channel applications, the FOT-CC and FOR-CC Fiber Optic Transmitter and Receiver provide point-to-point contact closure information over a single fiber optic cable.

For multi-channel applications, the EOTec 2000 fiber optic Multi-Channel Contact Closure transceiver modules are used to convert up to 10 contact closure inputs (switches, relays, etc.) into fiber optic signals for transmission over a single fiber optic link.
