GE IS230TRLSH2B – Mark VIe Relay Output Termination Board
Product Overview
The GE IS230TRLSH2B is a relay output termination board associated with GE’s Mark VIe turbine control platform. Available industrial automation references identify it with the related IS200TRLYH1BGG assembly and describe its function as a relay output interface for turbine and auxiliary equipment control.
In practical terms, the board provides relay-based switching between control-system logic and field devices such as solenoids, motors, pumps, and other discrete actuators. This makes it particularly relevant to turbine control cabinets where reliable discrete output handling is required. Mark VI/VIe terminal boards are designed to organize field wiring and interface I/O electronics with the cabinet-side control architecture. GE documentation also emphasizes dedicated terminal-board designs for different I/O functions and cabinet configurations.

Published supplier information should be treated as reference data for physical dimensions and weight; electrical ratings should be confirmed against the installed system documentation before procurement.
Key Features and Benefits — IS230TRLSH2B
- Relay-based output switching for discrete field control.
- Intended for GE turbine-control cabinet architectures.
- Supports applications involving pumps, fans, valves, solenoids, and other auxiliary equipment.
- Related to the IS200TRLYH1BGG relay termination-board assembly used in Mark VI/VIe applications.
- Provides a defined termination point between control electronics and field wiring.
- Useful as a replacement component for legacy turbine control systems where exact hardware matching is important.
Personally, I would not select this part based on the relay-board description alone. The suffix and related board number matter, because GE Mark VI family termination boards can look similar while having different field interfaces and electrical functions.

Installation and Maintenance — IS230TRLSH2B
Before replacement, record the existing board identification, wiring locations, terminal assignments, jumper configuration, and related I/O hardware. Power should be isolated according to the site maintenance procedure before removing the board.
Inspect relay terminals, connectors, PCB surfaces, and wiring for overheating, oxidation, loose connections, or mechanical damage. After installation, perform point-to-point wiring verification and functional testing of each affected output. For turbine protection or shutdown applications, follow the approved commissioning and proof-test procedure rather than relying on a visual inspection alone.
Product Warranty — IS230TRLSH2B
Warranty depends on supplier condition and procurement terms. Confirm whether the unit is new, refurbished, or surplus and request serial-number traceability, test documentation, and warranty coverage before ordering. For critical Mark VI/VIe applications, matching the complete GE part number and compatible assembly identification is recommended.
The GE IS230TRLSH2B is best treated as a dedicated turbine-control relay termination component, not a generic relay module. Exact hardware identification is the safer approach when restoring an existing GE control cabinet.
