COMNET FDC10RM1B overview

  • 1Description
Provided by third party:

The ComNet FDC10 Series bi-directional contact closure transceiver provides bi-directional transmission of contact closure over one multimode or single mode optical fiber. The transceiver has a contact input and a 0.5 amp contact output. The bi-directional contact closure module has two relay outputs and one relay input. One relay output follows the "relay input" at the remote end. When the remote "relay input" is shorted, the local relay output is closed and vice-versa. The second relay output is closed when "carrier" is detected from the remote end, this indicates that the optical fiber is connected and that the remote end has power and is operating.

Key Features
  • Transmits a single contact closure in one or two directions
  • 30 VDC, 0.5 amp relay output, normally open
  • Point-to-Point transmission architecture
  • Plug-and-play design ensures ease of installation requiring no electrical or optical adjustments
  • Relay contact for carrier detect (normally closed with carrier present)
  • Automatic resettable solid-state current limiters
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events
