Product Function Description

DS200DCFBG1BLC DCFB DC feedback board is an important signal acquisition component for Mark V excitation loop. It collects DC voltage and DC current feedback signals from the generator excitation unit, completes precision conversion and filtering processing, and transmits effective sampling data to the main controller.

Hardware jumpers on the board can adjust sampling range to adapt to different exciter parameters. LED indicators intuitively reflect the running state of the board, which is convenient for on‑site inspection and fault diagnosis. BLC hardware version optimizes the sampling circuit, improves the stability of feedback signal transmission, and provides accurate basis for generator excitation closed‑loop regulation and over‑current protection.

Product Details

Rack‑mount multilayer PCB plugs directly into Mark V cabinet slot, and needs to cooperate with supporting terminal board. Conformal coated circuit board resists dust, moisture and complex electromagnetic interference in power‑plant environment, meeting the requirement of long‑term continuous operation. The original manufacturer has ended production, and it is mostly used for unit maintenance and spare‑part replacement. ESD protection shall be done during installation, check hardware revision and jumper setting to ensure system compatibility.
