GE IS210MVRCH1A (also written as Ge1S210MVRCHIA) is a PWA (Programmable Wiring Assembly) component used in the GE Speedtronic Mark VI/VIe system. It is composed of two circuit boards:

• IS200MVRCH1A Base Board – Responsible for MVRC (Medium Voltage Relay Control), managing key high-voltage circuits such as start-up, shutdown, and isolation in gas or steam turbine systems.
• IS200HSLAH1A High-Speed Serial Link Board – Provides high-speed data communication, connecting various modules within the Mark VI system to enable rapid information exchange.

The assembly is mounted to the MVRC base using four support brackets and is equipped with multiple cable interfaces (JC, JAA, JBB, JCC, JDD, JAR, JAS, JAT, etc.), with optional interfaces such as JHH and JII to meet different field-wiring requirements.
