Srlys2A; Srly + Wrob - GE Mark VIeS System Manual

6.8.2 Operation

6.8.2.1 SRLYS2A

The SRLYS2A uses pluggable type terminals and has connectors JW1 and JW2 supporting option board connection.
Electrically, the SRLYS2A has the following circuit for each of the 12 relays:
Without an option board, the SOL terminal associated with each relay has no connection. SRLY is designed to support a
current rating of 5 A and voltage clearance greater than is needed for 250 V ac on all customer screw and JW1 circuits. The
relay rating is the limiting item for each application.

6.8.2.2 SRLY + WROB

Option board IS400WROBH1A adds capability to the SRLYS2A to yield a combination that has the same functionality as the
TRLYS1B terminal board when used simplex. Included are fused sensed power distribution to the first six relays and
dedicated power to the last relay. Electrically, the SRLYS2A plus IS400WROBH1A together have the circuitry displayed in
the following figure. IS400WROBH1A has default fuse values of 3.15 A. Connector JW2 and its connections to JA1 are
omitted for clarity.
