IS200SRLYH2A - SIMPLEX TB RELAY
Module manufactured by General Electric as part of the Mark VI/VIe Series used in gas turbine sppedtronic control systems
IS200SRLYH2A is a Simplex Relay Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE distributed turbine control systems. The Simplex Relay Output (SRLY) terminal board is a simplex S-type terminal board that accepts a PDOA/YDOA I/O pack and offers 48 customer terminals for 12 form C relay output circuits. The physical dimensions, customer terminal placements, and I/O pack mounting of SRLY are identical to those of other S-type terminal boards. A connected PDOA or YDOA I/O pack will be the highest component, allowing for double stacking of terminal boards. Each relay on SRLY feeds PDOA and YDOA its position using a single, isolated contact pair.
INSTALLATION:
A sheet metal carrier with SRLY and a plastic insulator installed on it is fastened to a cabinet with screws. Option boards can be plugged into SRLYH2A or SRLYS2A and are held in place by the connectors' force. The purpose of each terminal point in relation to the existence of an option board is described in the following table.
OPERATION:
There are two different groups of SRLY. Option board connectors JW1 and JW2 are absent from the SRLY1A and are replaced by fixed box terminals. With connectors JW1 and JW2, the option board connection on the SRLY2A is supported by pluggable type terminals. Each of the 12 relays in SRLYH2's electrical circuit is configured as follows:
SRLY Terminal Board Grouping
The SOL terminal connected to each relay has no connection in the absence of an option board. On all customer screw and JW1 circuits, SRLY is intended to support a current rating of 5 A and a voltage clearance greater than required for 250 V ac. The limiting factor for each application is the relay rating.
CONFIGURATION:
The SRLY terminal board doesn't have any jumpers. Six jumpers on option board WROBH1 are used to turn on or off power to a relay. With each of the six jumpers in position, boards are created. When a relay is to be utilized with dry contacts and no power distribution is intended, the jumper is removed from the board. The WROFH1 board is not connected to any jumpers. The terminal point selected as the relay common determines whether a series fuse is included or excluded for each relay. To enable direct use of the fuse voltage sensing circuit as a voltage detector, the WROF fuse connected with each relay may also be eliminated.
