8-CHANNEL OPTICALLY ISOLATED
CONTACT CLOSURE TRANSMITTER
The FDC8ISOT 8-Channel Contact Closure Transmitter unit provides up to eight
independent normally-open (NO) dry contact closures over one multimode or
single-mode optical fiber, when used in conjunction with the companion ComNet
model FDC8NLR Non-Latching Receiver or FDC8R Latching Receiver units. Each
of the contact closure inputs are optically isolated at 1500V to ground, for those
applications where high stray or transient voltages may exist. Microprocessor-
based logic in the FDC8ISOT Transmitter detects a customer-furnished switch
or contact closure, and encodes the closure into robust data packets that are
mapped and transmitted to the FDC8NLR Receiver. Packets received with
excessive bit errors will not result in random changes in the receiver relay
contact resting or actuated states, making this system ideal for mission-critical
remote switching applications. See Figure 3 on Page 3 for contact settings.
These transmitter modules incorporate status indicating LEDs for rapidly
providing a local indication of each contact closure channel and operating power.
See Figure 4 on Page 3 for an explanation of the LED indicators.
Packaged in the exclusive ComNet ComFit housing, these units may be either
shelf or rack-mounted, or may be DIN-rail mounted by the addition of ComNet
model DINBKT1 Adaptor Plate Kit. See Figure A on Page 4 for mounting
instructions.
See Figures 1 – 4 for complete installation information.
