ComNet Bi-Directional Contact Closure Transceiver

• Transmits a single contact closure in one or two directions
• Distances up to 69 km (43 miles)
• 30 VDC, 0.5 amp relay output, normally open
• Point-to-Point transmission architecture
• Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/lowline voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
• 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.
• FDC10(M,S)1(A,B) models are housed in a smaller-sized package for stand-alone mounting only, for use in those applications where space may be limited
• FDC10R(M,S)1(A,B) ComFit models may be utilized as a stand-alone package, or may be mounted within the ComNet C1 Card Cage, and is fully hot-swappable
• Indicating LEDs are provided for confirming equipment operating status. The relay position (open for RED and closed for GREEN) is indicated by separate bi-color indicators for each relay.
• Lifetime Warranty
