GE IS230SRLYH2A Mark VIe Simplex Relay Output Terminal Board

Product Description

Configured for discrete relay output interfacing in the GE Mark VIe control system, the General Electric IS230SRLYH2A (IS200SRLYH2AAA Simplex Relay Output Terminal Board) provides 12 Form C relay output circuits through field terminal connections. The board supports 48 customer terminals and interfaces with compatible PDOA or YDOA1 output packs. Each relay uses an isolated contact pair for its associated output circuit.

Hardware Specifications

Relay Output Architecture and I/O Integration

The IS230SRLYH2A provides 12 relay circuits with Form C contact arrangements. The board accepts compatible PDOA or YDOA1 output packs, which interface with the relay positions through the board's output-pack connections.

Each relay circuit uses an isolated contact pair. The board provides 48 customer terminal positions for external wiring. The supplied documentation also identifies differences between SRLY board variants: the SRLY1A uses fixed box terminals in place of option-board connectors JW1 and JW2, while the SRLY2A supports pluggable terminal connections for option boards.

The stated 125 VDC value requires verification against the applicable hardware manual before use as a relay contact voltage or load rating. The available information does not specify maximum switching current, contact material, or electrical life.

Frequently Asked Questions

Q: How many relay output channels does the IS230SRLYH2A support?

A: The board supports 12 relay output channels with Form C contact configurations and provides 48 customer terminal positions.

Q: Which output packs are compatible with this terminal board?

A: The supplied specifications identify PDOA and YDOA1 output packs. Confirm the exact output-pack model and hardware revision against the system configuration before installation.

Q: Can the IS230SRLYH2A be replaced while the system is powered?

A: Hot-swap capability is not confirmed by the supplied data. Follow the applicable GE Mark VIe maintenance procedure and isolate relevant power sources before removing or replacing the board.

Field Installation Guidelines

• Verify the board model, spare model, hardware revision, and output-pack compatibility against the approved system documentation.
• Isolate relevant power sources and follow site lockout/tagout procedures before installation or removal.
• Mount the board and its insulating components on the specified sheet-metal carrier using the approved cabinet hardware.
• Check relay terminal assignments and Form C contact configurations against the applicable wiring diagrams.
• Verify the permitted contact voltage and switching current before connecting external loads.
• Inspect the terminal connections and output-pack connectors for damage, contamination, or poor engagement.
• Route signal wiring separately from high-noise power conductors where practicable.
• Apply shield termination and grounding according to the cabinet design and GE installation documentation.
• Complete continuity checks and relay functional tests before returning the system to service.
