GE DS200XDSAG1ACC (XDSA Transducer Interface / Fuel Pressure Board)

Product Description

The GE DS200XDSAG1ACC is a transducer interface terminal board for GE Speedtronic Mark V turbine control systems, also known as LM fuel pressure management board. It acquires and conditions analog signals from fuel pressure sensors, LVDT, thermocouples and 4–20mA transmitters, converts raw field signals into digital data for the Mark V controller, and supports 125 VDC trip solenoid drive for safety protection. The ACC suffix represents revision C enhanced version with improved EMI resistance, widely used on LM series gas turbines.

FAQ

Q: What is the difference between DS200XDSAG1ACC and DS200XDSAG1A?
A: DS200XDSAG1ACC is Rev C upgraded variant of DS200XDSAG1A, with better EMI suppression and component upgrades.

Q: Can this board work on Mark VI or Mark VIe systems?
A: No, it is dedicated Mark V hardware, not compatible with Mark VI / Mark VIe architecture.

Q: What tests are required for refurbished units?
A: Power supply test, channel accuracy calibration, trip solenoid output test, RS422 communication test and visual solder joint inspection.
