Description
📦 Product Description
The GE DS200DDTBG2ABB is an LCI Auxiliary I/O Terminal Board designed for the GE Mark V turbine control system. It provides an interface for multiple auxiliary field input and output signals and is used as part of the signal-processing and termination architecture in compatible Mark V installations. The board supports a variety of signal types, including high-voltage AC inputs, high-current inputs, low-current inputs, 4–20 mA current-loop inputs, buffered analog outputs, 4–20 mA outputs, and digital I/O.
The DS200DDTBG2ABB is a revised version within the DS200DDTBG2 board family and includes multiple hardware revisions. It interfaces with the Mark V control architecture through associated boards such as the DS200ADMA and DS200DSPC. Its multiple terminal blocks, LEDs, test points, jumpers, relays, transformers, and signal-conditioning components support field wiring, monitoring, and auxiliary control functions.
This board is intended for qualified industrial control and turbine-system maintenance personnel. Because the DS200DDTBG2ABB is associated with high-voltage signal circuitry, the complete part number, hardware revision, wiring configuration, terminal assignments, and system compatibility should be verified before installation or replacement.
