WARRANTY

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.

Features

  • Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions, and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
  • Automatic Electronic Current Limiting
  • 30 VDC, 0.5 amp relay output, normally open
  • Relay contact for Carrier Detect (normally closed with carrier present)
  • Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.

Applications

  • Alarm Event Triggering
  • Building Automation and Environmental Control Systems
  • Fire and Alarm Systems
  • Gate Control
  • PIR Signal Transmission
  • Traffic Signal Control Equipment
