8-Channel Contact Closure Transmitter and Receiver
FDC8 SERIES
HARDENEDINCLUDED
The ComNet™ FDC8 Series contact closure transmitter and receiver provides
transmission of up to eight independent contact closures over one RS232 link or
optical fiber. Microprocessor-based logic sends the contact information in packets that
are ordered and encoded, ensuring extremely robust transmission. Packets that are
garbled, packets out of sequence, and transmission bit errors will not cause random
changes of state on the contact relays. Also, the mechanical latching relays maintain
their state even when the unit loses power. Each module incorporates power and
individual status indicating LEDs for monitoring confirmation of contact closure of each
of the eight channels. Packaged in the exclusive ComNet ComFit housing, these units
may be either wall or rack-mounted, or may be DIN-rail mounted by the addition of
ComNet model DINBKT1 or DINBKT4 adaptor plate.

† Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch
panels. Distance can also be limited by fiber bandwidth. ‡ For 50/125µm fiber, subtract 4 dB from the optical power budget.
