Product Introduction
IS400SRLYS2ABB Simplex Relay Output terminal board is a simplex S-type terminal board accepting a YDOA I/O pack and providing 12 form-C relay output circuits through 48 customer terminals. The SRLY has the same physical size, customer terminal locations, and I/O pack mounting as other S-type terminal boards. There will be no components higher than an attached I/O pack, permitting double stacking of terminal boards. Each relay on SRLY uses an isolated contact pair as position feedback to the I/O pack.

Product Details
How to use Simplex Relay Output:
One SRLY group is approved for use with the YDOA: the IS410SRLYS2A terminal board has pluggable, Euro style box-type terminal 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 sensed power 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 is included.
IS400SRLYS2A Installation：
SRLY and a plastic insulator mounts on a sheet metal carrier and is then mounted to a cabinet by screws. If an option board is used, it plugs onto SRLYS2A and is held in place by the force of the connectors.
• NC: normally closed contact of a form C relay
• COM: common point of a form C relay contact
• NO: normally open contact of a form C relay
• SOL: return circuit path for a solenoid that is powered by the relay board
• VSENSE: the input to a voltage sensor that looks between VSENSE and COM
• RETURN: return power path for devices powered by the WROG option
The SRLYS2A uses pluggable type terminals and has connectors JW1 and JW2 supporting option board connection.
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.
