The FDC80 contact closure transmitter and receiver provide transmission of up
to eight independent supervised contact closures over either one optical fiber or
two wire RS-485 link. 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. The receiver unit is offered in
both latching and non-latching relay configurations.

Multiple levels of supervision and receiver alarm control can be selected. See Figure
7 on Page 4 for switch settings.

Each module incorporates power and individual status indicating LED’s for monitoring
confirmation of contact closure of each of the eight channels. See Figure 8 on Page 4
for an explanation of the LED indicators.

These units are interchangeable between stand-alone or card mount configurations.
See Figure A on Page 7 for mounting instructions.

See Figures 1 – 11 for complete installation information, following the Application
Note on Page 6.
