ComNet FDC10M1A 2-Way Contact Closure Transceiver-A

Optimize remote switching and status monitoring in security and surveillance systems with the ComNet FDC10M1A bi-directional contact closure transceiver. This ComNet media converter transmits a single contact closure over one multimode or single-mode optical fiber, delivering reliable control between remote devices and central controllers. With a 30 VDC, 0.5 A relay output and carrier-detect feedback, installers get clear, actionable status that confirms fiber connectivity and remote power. The FDC10M1A supports long-range transmission (up to 43 miles / 69 km), making it ideal for perimeter security, traffic signal control, alarm panels, and access control networks that require robust, low-latency signaling. Built to meet NEMA TS-1/TS-2 environmental requirements and equipped with voltage transient protection and automatic resettable current limiters, this transceiver minimizes downtime and maintenance costs in demanding field deployments. Its compact, surface-mount, plug-and-play design speeds installation and reduces integration complexity in control cabinets and enclosures. For secure, low-voltage contact transmission across fiber in surveillance, monitoring, and control applications, specify the ComNet FDC10M1A media converter transceiver—contact us to discuss deployment options or to order.
