Product Details:

The GE IS200SDIIH1ADB, material part number MRP683026, is a high-reliability Contact Input Isolation Terminal Board (SDII) designed for GE Speedtronic Mark VI turbine control systems. This industrial control spare part serves as the field contact signal interface for digital input pack modules. As a reliable Turbine Control Module, it collects dry contact and wetting voltage status signals from circuit breakers, limit switches, protective interlock relays and auxiliary equipment. It provides optical isolation and surge suppression between field circuits and control rack internal circuits, isolating noise and transient voltage interference. It converts field contact signals into stable digital signals and transmits data to the main controller through the matched digital input module, for gas turbine and steam turbine interlock and status monitoring.

The GE IS200SDIIH1ADB Contact Input Isolation Terminal Board adopts conformal coated PCB to resist dust, moisture and vibration in harsh power plant environments. It is equipped with barrier terminal blocks and dedicated ribbon cable connectors for convenient field wiring and maintenance. The board supports simplex, dual and TMR redundant system architectures and VME rack mounting inside Mark VI control cabinet. Built-in channel diagnostic functions can detect open circuit, short circuit and signal loss faults. It is widely used in power generation and oil & gas industries for gas turbine, steam turbine control system maintenance, spare part replacement and system retrofit.
