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 for each
channel. 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.
See Figures 1 – 2 and A - B for complete installation information.
