The RLH 8 Channel Contact Closure DIN Fiber Link system provides a transmission of up to eight independent contact closure signals over one optical fiber. The system comprises a transmitter module and a receiver module, each in a compact DIN mount housing.

The system requires a 24~56VDC local power source at each end to provide power. The RX module includes a NC/NO alarm contact for system monitoring. Fiber optic cable is immune to RF noise, high voltages, and provides a transmission range of up to 15km/ 9 miles.

The DIN mount is designed to be installed onto a standard T35 (35mm) DIN rail.
