Comnet FDC10RS1A Bidirectional Contact Closure Rack Mount

Product Description

The COMNET FDC10RS1A is a bidirectional contact closure device designed for rack-mount installation in networking and signal transmission environments. Contact closure transmitters and receivers in this class carry dry-contact signals over fiber or network infrastructure, allowing remote sensing and control of switch states across distances where copper runs are impractical. The FDC10RS1A is a small-form unit built for rack deployment, making it suited for structured installations where space and organization matter. Licensed networking technicians and low-voltage integrators are the typical installers for this class of equipment.

The FDC10RS1A fits into rack-mounted networking equipment deployments, typically in commercial or industrial environments where contact closure signals from door contacts, alarm panels, relays, or similar dry-contact devices need to be extended or transmitted. Its small form factor supports installations where rack space is limited. The bidirectional Type A configuration allows two-way contact state communication, which is relevant in access control, security, and automation applications.

Installation Notes

Installation of contact closure transmitter and receiver equipment is typically performed by licensed low-voltage technicians or network infrastructure installers. De-energize all connected control circuits and signal sources before making or breaking connections. Follow applicable NEC low-voltage wiring guidelines and any local AHJ requirements for signal and control wiring. Verify contact closure polarity and signal direction requirements before commissioning.
