Transmit 8 Contact Closures Over a Single Fiber​
The RLH 8 Channel Contact Closure fiber link card provides a transmission of up to eight independent contact closure signals over one optical fiber. The transmitter card provides the electrical-to-optical interface between dry contact closure relay input and a fiber strand.
The receiver card provides the optical-to-electrical interface between a fiber strand and normally-open relay contact output. Both cards are powered by a 24-56VDC source and the receiver card provides LED indicators to display relay conditions, power, and fiber carrier receive.
This fiber link card is designed to be installed into any of the RLH Fiber Link Card Housings, and occupies a single card slot.
