The IS200SRTDH2A is a Compact RTD (Resistance Temperature Detector) Terminal Board developed by General Electric (GE) for integration into the GE Mark VIe turbine control system platform. This terminal board is specifically engineered for precise temperature monitoring using RTDs and supports multiple channels of input for critical turbine and auxiliary system components.

Used extensively in gas and steam turbines, this board enables accurate and reliable temperature acquisition from field-mounted RTDs. It supports 2-wire and 3-wire RTD configurations, ensuring compatibility with industry-standard sensors while minimizing measurement errors due to lead resistance or electrical noise.

The IS200SRTDH2A connects directly to an RTD I/O pack (such as IS220PRTDH1A), providing the analog interface between field sensors and the control system. The board is DIN-rail mountable, making installation straightforward in compact control enclosures. It’s built to operate in harsh industrial environments, with robust design characteristics to withstand high vibration, temperature extremes, and electrical interference.

This terminal board includes well-labeled screw terminals for easy field wiring and features built-in shielding and grounding provisions that reduce electrical noise and improve signal integrity. It typically accommodates up to 10 RTD inputs, which are routed to the associated I/O pack for conversion and processing by the Mark VIe controller.

The SRTDH2A plays a vital role in turbine protection and performance monitoring by ensuring accurate real-time temperature data. This data is used by the control system to perform functions such as load shedding, overheating protection, efficiency optimization, and predictive maintenance alerts.

Built with high-quality industrial-grade components, the IS200SRTDH2A ensures long operational life and minimal maintenance, supporting the reliable operation of the overall GE Mark VIe control system. Its compact footprint makes it ideal for applications where space-saving is essential without compromising functionality.

Whether used in new installations or as a replacement in existing GE Mark VIe environments, the IS200SRTDH2A provides trusted and accurate RTD input capability, forming an essential component in the thermal monitoring infrastructure of power generation systems.
