ABB 3BHE003604R0102ABB UNITROL Excitation System Printed Circuit Board (PCB Assembly)
Signal conditioning and data transmission for synchronous generator UNITROL excitation controllers. Converts analog voltage/current signals from generator stator, rotor and transformer into digital signals. Provides isolation, filtering and surge protection. Executes auxiliary closed-loop regulation logic for AVR, participates in reactive power compensation and excitation limit protection. Acts as hardware bridge between power sampling circuits, thyristor rectifier units and central control logic boards. Embeds self-diagnostic circuits to detect board faults and signal loss.
