GE 377A9719G001 PCB Signal Conditioning Board

Product Description

Model: 377A9719G001, GE Speedtronic gas turbine control system PCB signal conditioning board, signal interface card for Mark VI / Mark VIe gas turbine control cabinets. The board integrates signal acquisition, filtering, isolation and conversion circuits. It pre-processes analog signals from field sensors, conditions temperature, pressure, vibration and other sensor signals and sends them to gas turbine controller for process parameter acquisition and noise isolation. Equipped with multiple terminal connectors and conformal coating. It is dedicated spare part for GE gas turbine control cabinets. Original production discontinued, available stock mainly used and professionally refurbished & tested units.

Application

Used for GE Mark VI / Mark VIe gas turbines and combined cycle power plant control systems. It collects analog signals from field pressure, temperature and vibration transmitters, performs signal isolation, noise reduction and level conversion, then transmits data to main turbine controller for unit start/stop, fuel control and over-limit protection logic. Typical applications: gas power plants, combined cycle power stations and industrial captive power plants. Suitable for unit overhaul, control system troubleshooting, spare replacement and legacy cabinet retrofit.
