DS200DDTBG2A GE Mark V LM LCI Auxiliary I/O Terminal Board

Product Description

The DS200DDTBG2A is an LCI Auxiliary I/O Terminal Board manufactured by General Electric for the Mark V LM turbine control system. It provides external connections for auxiliary input and output signals, supporting signal interfacing between field devices and the control electronics. Furthermore, its 12-channel configuration and 28 VDC power supply support auxiliary signal handling within the LCI control architecture.

Technical Specifications

Functional Description

The DS200DDTBG2A provides terminal connections for auxiliary I/O signals in the GE Mark V LM control architecture. It supports the interface between external signals and the control electronics, allowing the system to receive and process auxiliary input information and manage associated output signals.

The DDTB board interfaces with the DS200ADMA analog-to-digital module daughterboard, which mounts on the DS200DSPC digital signal processor control board. According to the supplied functional description, the ADMA supplies power to the DDTB through the board interconnection.

Signal Interface and Configuration

The board supports external connections for several signal types, including:

• High-voltage signals.
• Contact input and output signals.
• Current measurement using Hall-effect devices.
• High-current current transformer (CT) signals.

Furthermore, the described interface architecture uses high-density connectors and a ribbon cable to connect the DDTB and ADMA assemblies. Signal conditioning, scaling, buffering, and isolation are identified as functions of the DDTB interface arrangement.

G1 and G2 Version Differences

The DS200DDTB family includes G1 and G2 versions. The G2 version does not provide some of the functionalities available on the G1 version. Therefore, maintenance teams should check the complete board number and revision before selecting a replacement. Do not assume that the two versions have identical I/O capabilities.
