Product Overview

DS200TCQAG1B (TCQA board) is RST analog I/O circuit board for GE Speedtronic Mark V gas‑turbine control system. It conditions and acquires multi‑type field analog signals including LVDT valve‑position feedback, thermocouple temperature, vibration sensors and 4‑20 mA process signals; meanwhile outputs drive signals to servo‑valves for turbine‑valve actuation. This legacy gas‑turbine spare PCB is end‑of‑production; available as rebuilt / refurbished and new‑old‑stock spare parts for gas‑turbine‑control‑system maintenance.

Application Notes

‑ Install inside GE Mark V turbine‑control rack. ‑ Strictly match signal‑wiring to board terminal definitions. ‑ Observe ESD protection before board replacement. ‑ Typical deployment: gas‑turbine power‑station, combined‑cycle power‑plant control‑cabinet spare‑part stocking.
