Description
🔧 Product Description
The GE General Electric DS200DDTBG1A, also identified as DS200DDTBG1ABB, is an LCI Auxiliary I/O Terminal Board used in GE Mark V and LS2100 control applications. The DDTB board provides termination, signal conditioning, scaling, buffering, and isolation for auxiliary I/O signals. It interfaces with the DS200ADMA analog-to-digital module mounted on the DSPC control board and can handle high-voltage AC inputs, high-current CT signals, low-current LEM signals, 4–20 mA signals, and other auxiliary voltage inputs. The board includes multiple test points and LED indicators for system monitoring and maintenance.

Q: Is DS200DDTBG1A still in production?
A: It belongs to the legacy GE Mark V/LS2100 generation and is generally handled as a maintenance and replacement component rather than a current-generation board.
🛡️ Safety Notes
• Disconnect and isolate all applicable power before handling the terminal board.
• Use appropriate ESD protection when installing or removing the PCB.
• Verify all field wiring and terminal assignments before energizing the system.
• High-voltage and high-current inputs require appropriate isolation and safety procedures.
• Confirm the complete part number and hardware revision before replacement.
• Installation and maintenance should be performed by qualified industrial automation personnel.
