Supports simplex, dual and TMR triple‑modular redundant architectures, realizes turbine interlock protection, trip logic and SOE sequence‑of‑event recording function.

Product Details

The IS230TCISH6C is DIN‑rail type dry‑contact input terminal board for GE Mark VIe Speedtronic distributed turbine control system.

This terminal board adopts compact DIN‑rail installation structure, equipped with high‑density screw terminals for field dry‑contact device wiring. Each channel integrates surge‑suppression and EMI filter circuits to restrain voltage spike interference brought by long‑distance field cables. It converts field contact status into stable discrete signals and transmits them to matched PDIA I/O processing pack for logic calculation, providing reliable switch‑state data for turbine safety protection and interlock control.

Built‑in channel self‑diagnosis function can detect circuit open‑circuit, short‑circuit and signal abnormality, and upload fault alarm records to turbine controller. Conformal coated circuit board improves anti‑vibration and anti‑interference performance, adapts to harsh electromagnetic environment of power‑plant turbine hall, meets hazardous‑area application requirements.

It belongs to key discrete signal termination spare‑part for Mark VIe turbine control system, widely used in overhaul and renovation projects of gas‑steam turbine generating units.

It is important spare hardware for turbine discrete signal loop debugging and defective IS230TCISH6C board replacement.
