I/O modules

The GE DS200TCDAG1B DS200TCDAG1BCB manages discrete I/O signals for Mark V turbine control systems. You can install this board into the main turbine control cabinet. It interfaces with field devices and status indicators. This board suits gas and steam turbine monitoring and sequencing applications.

Technical Specifications and Hardware Layout

The GE DS200TCDAG1B DS200TCDAG1BCB measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCDAG1B DS200TCDAG1BCB weighs approximately 0.41 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. Three terminal blocks handle field wiring for I/O signals. Six test points allow signal monitoring with a multimeter.

Digital I/O Specifications

The GE DS200TCDAG1B DS200TCDAG1BCB provides eight digital input channels. It accepts 24 V DC signals from switches and pressure transmitters. This board also delivers eight digital output channels for actuator control. Each output switches 0.5 A at 24 V DC continuously. Consequently, this board handles turbine auxiliary systems and alarms. 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 DS200TCDAG1B DS200TCDAG1BCB 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.
