GE IS410SRLYS2A SIMPLEX RELAY Terminal Board
Description:
IS410SRLYS2A is belong to GE Simplex Relay Output (SRLY) terminal board，it is a simplex S-type terminal board accepting a YDOA I/O pack andproviding 12 form-C relay output circuits through 48 customer terminals. The SRLY has the same physical size, customerterminal locations, and I/O pack mounting as other S-type terminal boards. There will be no components higher than anattached I/O pack, permitting double stacking of terminal boards. Each relay on SRLYuses an isolated contact pair as positionfeedback to the I/O pack.
One SRLY group is approved for use with the YDOA: the IS410SRLYS2A terminal board has pluggable, Euro style box-typeterminal blocks and two connectors that can accept a variety of optional daughterboards.
There are three optional daughterboards available to plug onto the SRLYS2A:
•   IS400WROBH1A turns SRLY into the functional equivalent of the TRLYS1B. This option provides fused and sensedpower distribution to the first six relays and dedicated power to the last relay.
•   IS400WROFH1A puts a single fuse in series with each relay common connection. Fuse voltage feedback is included.
•   IS400WROGH1A distributes power from an input connector to each relay through a single fuse. Fuse voltage feedback isincluded.
