Core Function

DS200TCEAG1ACB TCEA exciter terminal board is special signal interface hardware for GE Mark V and EX2000 excitation system. It is used for termination, filtering and transmission of exciter feedback signals and field analog signals. It cooperates with SDCC drive control board to complete signal routing between excitation drive unit and control logic. The detachable terminal block simplifies field wiring and replacement maintenance. Built‑in filter circuit suppresses on‑site electromagnetic interference, ensures accurate and stable signal transmission for excitation regulation and protection interlock.

Product Details

DS200TCEAG1ACB belongs to TCEA series exciter termination board of GE Speedtronic Mark V / EX2000 excitation control system.

This rack‑mount PCB board is installed inside EX2000 excitation cabinet. It receives exciter feedback signals from field equipment, performs noise filtering and signal distribution, and transmits processed signals to SDCC drive control board. Removable terminal block supports quick disassembly without re‑wiring, greatly improving on‑site maintenance efficiency. LED indicators help maintenance staff quickly judge channel signal status. Conformal coated circuit board has excellent anti‑vibration, moisture‑proof and anti‑interference performance, adapting to harsh power‑plant cabinet environment. Widely applied in gas‑steam turbine generator EX2000 excitation system for exciter signal termination and conditioning processing.

It belongs to critical signal termination spare‑part for EX2000 excitation system, widely used in overhaul and renovation projects of power generation units. It is important spare hardware for signal loop debugging and defective DS200TCEAG1ACB board replacement.
