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.
- Available with ST or SC Connectors
- Convenient LED status indicators
- Single and Multimode fiber models available
- RX side includes alarm contact for status monitoring
- Alarm contact may be set to Normally Open or Normally Closed
- DC power is not polarity sensitive, simplifying wiring duties
- Environmentally rugged with wide operating range: -40˚F to +158˚F (-40˚C to +70˚C)
- Single slot RLH Fiber Link Card form factor allows up to 12 cards in a 12 card housing, or multiple housings for larger installations
- Limited Lifetime Warranty
- Made in USA
