I/O modules

The GE DS200TCDAH1B DS200TCDAH1BHE processes discrete field signals for Mark V turbine control systems. You can install this board into the main turbine control cabinet. It reads switch inputs and drives indicating lamps. This board suits gas and steam turbine sequencing and status monitoring applications.

Technical Specifications and Hardware Layout

The GE DS200TCDAH1B DS200TCDAH1BHE measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCDAH1B DS200TCDAH1BHE weighs approximately 0.44 kilograms. A single multilayer PCB holds all input and output circuits. The board contains no energy storage capacitors or batteries. Two 50-pin ribbon connectors provide system interface connections. Four terminal blocks handle field wiring for I/O signals. Six test points allow signal monitoring with a multimeter.

Digital I/O Specifications

The GE DS200TCDAH1B DS200TCDAH1BHE provides twelve digital input channels. It accepts 24 V DC signals from limit switches and pushbuttons. This board also delivers twelve digital output channels for actuator control. Each output switches 0.5 A at 24 V DC continuously. Consequently, this board handles turbine valve status and pump control. Input channels include programmable debounce filters for noise rejection. Output channels provide short-circuit protection for fault tolerance. Optical isolation separates the field side from the backplane logic.

Installation and Diagnostic Features

You must insert the GE DS200TCDAH1B DS200TCDAH1BHE 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, input status, and output activity 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.
