GE IS200TPROH1CBB Technical Specification
Model: IS200TPROH1CBB
Manufacturer: General Electric (GE)
Series: Mark VI (Speedtronic)
Type: Emergency Protection Terminal Board
1. General Description
The GE IS200TPROH1CBB is a critical terminal board for the GE Speedtronic Mark VI gas turbine control system. It serves as the interface for emergency protection signals, connecting and conditioning inputs from key sensors (such as MPU speed probes, PTs, and 4-20mA loops) and feeding them to the main protection processor (PPRO/VPRO). It is the primary physical I/O termination for turbine overspeed, vibration, and other emergency shutdown logic.
