INSTALLATION AND OPERATION MANUAL

FDC24NL[SFP] Series

24-CHANNEL DUPLEX CONTACT CLOSURE TRANSCEIVER

The ComNet FDC24NL Series contact closure transceiver units provide transmission

of up to twenty four independent duplex dry switch or relay contact closures using

a single SFP optical port or any four-wire RS-422 copper circuit. The FDC24NL Series

supports an integrated field expandable RS-422 data bus allowing up to 12 uniquely

addressed units to be connected to the bus providing up to 288 unique duplex

contact closures over a single SFP optical port or RS-422 copper circuit.

The contact closure information is sent 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. One relay can be optionally re-purposed as a summary fault

alarm contact and is triggered in the event that the unit loses fiber or RS-422 bus

communications. The FDC24NL series is offered with non-latching solid state relays.

Each module incorporates link and individual status indicating LEDs for monitoring

confirmation of contact closure input and output of each of the twenty four 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.
