Specifications

Description

IS230SNRLH2A IS200SRLYH2AAA is a Simplex Relay Output Terminal Board manufactured and designed by General Electric as part of the Mark Vle Series used in GE distributed turbine control systems. The Simplex Relay Output (SRLY) terminal board is desiqned as a simplex S-type board that accommodates either a PDOA or YDOA I/O pack. It features 12 form C relay output circuits distributed across 48 customer terminals. The SRLY maintains the same physical dimensions, terminal placements, and I/O pack mounting configurations as other S-type terminal boards. Its design ensures that no components exceed the height of the attached I/O pack, allowing for double stacking of the terminal boards. Each relay on the SRLY utilizes an isolated contact pair to provide position feedback to the I/O pack. The model comes equipped with pluggable Euro style box-type terminal blocks and two connectors that can support various option boards.

Applications

Power Plants: As a key component of the Mark VIe control system, it controls solenoid valves, interlocking pumps, and alarms for large gas turbines or steam turbines.

Chemical Plants: In complex processes, it executes safety interlock logic and drives high-power relays on critical production lines.

Oil Refineries: Used for distributed control of crude oil processing and hydrogenation units, ensuring signal isolation and stable output outside explosion-proof areas.

Steel Plants: Suitable for converter or rolling mill control systems in harsh environments, driving high-frequency automated machinery.

Natural Gas Compressor Plants: Used in booster stations of long-distance pipelines to control the start-up and shutdown logic and status feedback of compressor units.

Seawater Desalination Plants: Responsible for the logic switching control of large-scale water treatment pumps and valves.

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 into SRLYH2AAA and is held in place by the force of the connectors.

OPERATION

There are two different groupings of SRLY. Option board connectors JW1 and JW2 are absent from the SRLYH2AAA and are replaced by fixed box terminals. With connectors JW1 and JW2, the option board connection on the SRLYH2AAA is supported by pluggable type terminals. 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 ratina of 5 A and a voltaae clearance qreater 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.sWoc has the largest stock of GE Mark Vle Distributed Control System Replacement Parts.

FAQ

Q: What is the IS230SNRLH2A IS200SRLYH2AAA Simplex Relay Output Terminal Board (SRLY)?
A: The SRLY is a simplex S-type terminal board that accepts a PDOA or YDOA I/O pack and provides 12 form C relay output circuits through 48 customer terminals.

Q: How is the terminal board IS230SNRLH2A IS200SRLYH2AAA installed?
A: The board mounts on a plastic insulator attached to a sheet metal carrier, which is then secured to a cabinet using screws. If using an option board, it plugs into the terminal board and is held in place by the connectors.
