Core Function

DS200LDCCH1ANA LDCC drive control LAN communication board is the upgraded revision hardware for GE EX2000 excitation system. It adopts four‑processor collaborative architecture to process drive logic, motor control and customer I/O signal conversion. It realizes real‑time data interaction between Directo‑Matic 2000 exciter drive unit and Mark V turbine main control system through LAN communication channel. Non‑volatile flash‑based PROM stores drive configuration parameters and embedded application software. It reserves local debugging interface together with hardware and software dual reset mechanism, completes excitation drive regulation, field signal acquisition and comprehensive fault diagnosis. It is the core control carrier for generator excitation adjustment, ensures long‑term stable operation of excitation drive unit under complex power‑plant working conditions.

Product Details

DS200LDCCH1ANA belongs to LDCC series drive control communication board of GE EX2000 excitation control system, hardware pin‑to‑pin compatible with DS200LDCCH1AGA, requires matching firmware version when replacingDirect Tur...。

This multi‑processor integrated board is installed inside EX2000 excitation cabinet. Four independent on‑board processors undertake separate computing tasks for peripheral I/O processing, drive operation and motor control. The LAN control processor manages real‑time network data exchange for excitation drive equipment. Non‑volatile PROM retains key configuration data even under power‑off condition. Hardware and software double reset mode supports quick on‑site fault recovery. On‑board LED status lamps help maintenance engineers quickly judge board running condition and locate abnormal points. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant excitation cabinet. Widely deployed in gas‑steam turbine generator EX2000 excitation system for excitation drive control and network data communication processing。

It belongs to critical drive control spare‑part for EX2000 excitation system, widely used in overhaul and renovation projects of power generation units. It is important spare hardware for drive loop debugging and defective DS200LDCCH1ANA board replacement.
