I/O modules

The GE DS200TBQAG1A DS200TBQAG1ABB provides termination points for RST system signals in Mark V turbine controls. You can install this board into the main turbine control cabinet. It connects field wiring to the RST processing boards. This board suits gas and steam turbine signal termination applications.

Technical Specifications and Hardware Layout

The GE DS200TBQAG1A DS200TBQAG1ABB measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TBQAG1A DS200TBQAG1ABB weighs approximately 0.33 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 RST 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 DS200TBQAG1A DS200TBQAG1ABB provides 24 termination points for RST system signals. It accepts 24 V DC discrete inputs and 4 to 20 mA analog loops. Each channel includes a surge suppression circuit for transient protection. Consequently, this board shields sensitive RST processing circuits from damage. The board provides individual channel labeling for easy identification. Shield terminals allow grounding of cable shields for noise reduction. The terminal board requires no external power for operation.

Installation and Diagnostic Features

You must insert the GE DS200TBQAG1A DS200TBQAG1ABB 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.
