I/O modules

The GE DS200TBQCG1A DS200TBQCG1ABB terminates analog field signals for Mark V RST systems. You can install this board into the main turbine control cabinet. It provides connection points for pressure, temperature, and flow transmitters. This board suits gas and steam turbine analog signal termination applications.

Technical Specifications and Hardware Layout

The GE DS200TBQCG1A DS200TBQCG1ABB measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TBQCG1A DS200TBQCG1ABB weighs approximately 0.36 kilograms. A single multilayer PCB holds all termination and conditioning circuits. The board contains no energy storage capacitors or batteries. Two 50-pin ribbon connectors provide interface to analog processing boards. Five terminal blocks handle field wiring terminations. Six test points allow signal monitoring with a multimeter.

Termination Specifications and Signal Conditioning

The GE DS200TBQCG1A DS200TBQCG1ABB provides 16 termination points for analog field signals. It accepts 4 to 20 mA loops and RTD sensor inputs. Each channel includes a surge suppression circuit for transient protection. Consequently, this board shields sensitive analog processing circuits from damage. The board provides individual channel labeling for easy identification. Shield terminals allow grounding of cable shields for noise reduction. The termination board requires no external power for operation.

Installation and Diagnostic Features

You must insert the GE DS200TBQCG1A DS200TBQCG1ABB firmly into a dedicated Mark V rack slot. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. Six front LEDs show power and termination status clearly. For troubleshooting, use the six test points with a multimeter. Always power off the system before removing or inserting the board. The operating temperature range spans from -20°C to +55°C reliably.
