PLCs, Power Supplies & Others

The GE DS200TCQAG1A DS200TCQAG1AEC processes analog signals for Mark V turbine control systems. You can install this board into the main turbine control cabinet. It interfaces with field transmitters and final control elements. This board suits gas and steam turbine regulation applications.

Technical Specifications and Hardware Layout

The GE DS200TCQAG1A DS200TCQAG1AEC measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCQAG1A DS200TCQAG1AEC weighs approximately 0.51 kilograms. A single multilayer PCB holds all analog conversion and interface circuits. The board contains no energy storage capacitors or batteries. Two 50-pin ribbon connectors provide system interface connections. Four test points allow signal monitoring with oscilloscope probes. Six status LEDs display board operating conditions.

Analog I/O Specifications and Performance

The GE DS200TCQAG1A DS200TCQAG1AEC provides six analog input channels. It accepts 0 to 10 V DC or 4 to 20 mA field signals. This board also delivers two analog output channels for actuator control. Each output generates 4 to 20 mA signals with 12-bit resolution. Consequently, it provides precise positioning of turbine control valves. Accuracy stays within 0.25 percent of full scale at 25°C. The board includes built-in low-pass filters for noise rejection. Optical isolation separates analog circuits from the digital backplane completely.

Installation and Diagnostic Features

You must insert the GE DS200TCQAG1A DS200TCQAG1AEC firmly into a dedicated Mark V rack slot. Transitioning to testing, use the four test points for signal verification. Six front LEDs show power, input status, and output activity clearly. For troubleshooting, use a multimeter at the test points. Always power off the system before removing or inserting the board. The operating temperature range spans from -20°C to +55°C reliably.
