SVS-1 External Relay Interface
Relay Interface - T170/TS1/TS2 Cardfile
Relay Interface - Shelf Mount
Sensing and Systems Integration Solutions
The Relay Interface (SVS-RI) connects to the RS-232 port on each SVS-1 Processor DSP board using an RJ-45 to RJ-45 serial cable.

The function of the Relay Interface is to acquire the bit-serial relay message stream from the SVS-1 and convert the message to physical opto-coupled relay signals. High intensity LED's indicate true presence in the each zone. These signals are open collector vehicle presence signals and are brought out on individual conductors or on a card edge connector.

A jumper routing matrix allows any of the vehicle presence relays to be routed to any of the 4 card-edge relay contacts. Routing of additional relays is via a ribbon cable to optional daughter cards (SAS-RLY-332-01) in adjacent slots. Dual RJ-45 ports allow "daisy chaining" of multiple Relay Interfaces.
