8-ChANNEL CoNtACt CLoSuRE NoN-LAtChING RECEIVER
the FDC8NLR contact closure receiver provides transmission of up to eight
independent contact closures over one 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.
the solid-state non-latching relays default to a normally open state in the event of
power loss or loss of optical signal. See Figure 3 on Page 3 for contact 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 5 on Page 3 for an explanation of the LED indicators.
these units are interchangeable between stand-alone or card mount
configurations. See Figure A on Page 4 for mounting instructions.
See Figures 1 – 5 for complete installation information.
