Core Function
Primary trip I/O pack for Mark VI turbine control system. It receives overspeed and emergency shutdown signals transmitted from TRPA terminal board, completes signal acquisition, filtering and logic judgment. Supports TMR triple‑modular redundant voting function, realizes turbine overspeed protection, emergency trip and safety interlock processing, ensures fast and reliable protection action under abnormal operating conditions of the unit.
Product Details
The IS200PTURH1B (336A5026ADP12) is primary trip I/O pack for GE Speedtronic Mark VI turbine control system.
This VME rack‑mounted I/O pack must work with TRPA trip terminal board, cannot operate independently. It processes critical safety signals from turbine field side, adopts stable signal sampling circuit to restrain industrial interference. Multi‑channel LED indicators can feedback channel running status in real‑time, convenient for on‑site fault location and maintenance. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power plant turbine hall. It is widely applied in simplex and TMR triple‑modular redundant turbo‑generator unit protection cabinets.
It belongs to core safety spare‑part for Mark VI turbine control system, widely used in overhaul and renovation projects of power generation units.
It is important spare hardware for turbine trip loop debugging and defective IS200PTURH1B pack replacement.
