Comnet FDC10S1A Specsheet

Bi-Directional Contact Closure Transceiver

FDC10 SERIES

HARDENEDINCLUDED

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

› 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

APPLICATIONS

› Alarm Event Triggering

› Building Automation and Environmental Control Systems

› Fire and Alarm Systems

› Gate Control

› PIR Signal Transmission

› Traffic Signal Control Equipment
