FEATURES

› Transmits up to eight independent supervised or

unsupervised dry switch or relay contacts over one optical

fiber, or via a 2-wire RS-485 point-to-point copper circuit

› Microprocessor-based logic and latching relays in the

receiver unit eliminate random contact closure states in the

event of a loss of the link, or a loss of prime operating power

› Tested and certified by an independent laboratory for full

compliance with the environmental requirements (ambient

operating temperature, mechanical shock, vibration, humidity

with condensation, high-line/low-line voltage conditions and

transient voltage protection) of NEMA TS-1/TS-2 and the

Caltrans Specification for Traffic Signal Control Equipment

› Indicating LEDs for monitoring power, contact closure status,

and summary fault

› Automatic resettable solid-state current limiters

› Hot-swappable rack modules

› Interchangeable between stand-alone or rack mount use –

ComFit

› Lifetime Warranty

™

FDC80 Series contact closure transmitter and receiver units provide

transmission of up to eight independent supervised or unsupervised dry switch or

relay contact closures over a single optical fiber, or any two-wire RS-485 copper circuit.

Microprocessor-based logic transmits the contact closure information in packets that

are ordered and encoded, ensuring extremely robust and reliable transmission. Packets

that are garbled, or packets out of sequence with transmission bit errors will not cause

random changes of state in the FDC80R receiver unit relays. The supervising function

in the FDC80T transmitter allows for the detection of short and open circuit conditions,

and normally open or normally closed contact inputs are supported. System faults

are displayed via LED status indicators, and user-programmable summary fault alarm

contacts are triggered in the FDC80R receiver unit. The FDC80R receiver is offered in

both latching and non-latching relay configurations. External series and shunt resistors are

included for each of the 8 contact input channels, for contact supervision.
