DS200TCQAG1A Analog Module | GE Mark V Speedtronic Turbine I/O

Product Description

The GE DS200TCQAG1A Analog I/O Board delivers reliable signal processing for GE Mark V Speedtronic turbine control systems. It conditions and scales analog signals from terminal boards R1, R2, and R3, including thermocouples, LVDTs, servo valves, vibration sensors, and generator outputs. Moreover, the board integrates seamlessly with turbine control processors via the VME backplane, ensuring timely and accurate digital communication between field devices and control logic. Its rugged PCB construction with diagnostic LEDs allows continuous operation in demanding industrial environments.

Engineers value this board for its compatibility with both gas and steam turbines, wide operating temperature range, and high reliability under harsh conditions. In addition, its compact design allows easy installation in standard Mark V racks, providing consistent performance without modifying existing turbine infrastructure. Therefore, it serves as an ideal solution for upgrades, replacements, or expansions within industrial control systems.
