Product Function Description

DS200TCQAG1BHF‑W01 TCQA board is core discrete signal processor for Mark V turbine system. It receives feedback signals from limit switches and relay contacts, transfers isolated digital data to main CPU, and outputs switching commands to drive solenoid valves and field relays for unit interlock and sequence logic.

On‑board jumpers adjust input threshold and output mode. LED array shows real‑time channel status. BHF‑W01 revision upgrades hardware and firmware for better noise immunity under heavy electromagnetic environment, ensuring reliable execution of turbine trip, protection and auxiliary equipment interlock logic.

Product Details

Rack‑mount multilayer PCB fits inside Mark V cabinet slot and works with matched digital terminal board. Conformal coating protects circuit against dust, moisture and electromagnetic disturbance for long‑term plant operation. Original product is end‑of‑life, commonly used for unit retrofit and maintenance replacement. Please verify firmware version during installation for full system compatibility.
