Product Function Description

DS200DCFBG1BNC DCFB board is dedicated signal processing board for Mark V excitation loop. It samples DC voltage and current feedback signals from exciter unit, performs isolation, conversion and filtering, and sends processed data to main controller for closed‑loop excitation monitoring. On‑board jumpers adjust signal range for different exciter units. LED indicators show real‑time working status. BNC revision optimizes sampling circuit for higher measurement accuracy and noise immunity, providing reliable data for excitation regulation and over‑current protection.

Product Details

Rack‑mount multilayer PCB fits inside Mark V cabinet slot and works with matched terminal board. Conformal coating protects circuit board from dust, moisture and heavy electromagnetic interference for long‑term continuous operation. Original part is end‑of‑life, widely used for unit maintenance and spare‑part replacement. Please confirm hardware revision and jumper range setting before installation for system compatibility.
