DS200DDTBG2A GE Module Parts LCI Auxiliary I/O Terminal Board
The GE DS200DDTBG2A is an LCI Auxiliary I/O Terminal Board used in GE LS2100 static starter and related turbine control applications. Identified by the functional acronym DDTB, it provides signal conditioning, isolation, and interfacing for auxiliary analog and digital signals.
The board connects to the DS200ADMA Analog-to-Digital Option Board through high-density ribbon cable connectors. It processes field signals and makes them available to the control system, supporting the monitoring and control functions required by industrial drive and turbine-starting applications.
The DS200DDTBG2A is the G2 version of the DDTB board. Its detailed configuration and differences from the G1 version should be checked against GE manual GEI-100219.

The DS200DDTBG2A provides termination and interfacing for auxiliary input and output signals. It connects field wiring and signal-conditioning circuits to the associated control hardware.
The board provides buffering and signal conditioning for analog signals. Its inputs accommodate different signal types, including high-voltage AC signals, CT signals, and LEM transducer signals.
Eight isolated universal digital inputs allow the system to monitor external contact and voltage signals. These inputs can be used for equipment status, interlocks, and auxiliary operating conditions.
Two Form C relay outputs and four optically isolated outputs support external control and status signaling. The relay outputs can be used where higher switching capacity is required, subject to the specified electrical ratings.
Isolation and signal-conditioning circuits help protect control electronics from field-side electrical disturbances and support reliable signal transmission.
The DS200DDTBG2A is an LCI Auxiliary I/O Terminal Board with the functional acronym DDTB. It is used in GE LS2100 control applications to interface and condition auxiliary analog and digital signals.
It is associated with GE LS2100 static starter and LCI applications. Confirm the exact system configuration before selecting a replacement.
The DS200DDTBG2A interfaces with the DS200ADMA Analog-to-Digital Option Board through high-density ribbon cable connections.
The board is listed with four buffered analog outputs, identified as TP14 through TP17.
The board provides eight isolated universal digital inputs for monitoring external voltage and contact signals.
