Transmit 4 Contact Closures Over a Single Fiber
The RLH 4 Channel Contact Closure Fiber Optic Link system provides a transmission of up to four 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.
