PLCs, Power Supplies & Others

The GE DS200TCQBG1A DS200TCQBG1AFB expands analog input and output capacity for Mark V turbine controls. You can install this board into the main turbine control cabinet. It interfaces with field sensors and final control elements. This board suits gas and steam turbine monitoring and regulation applications.

Technical Specifications and Hardware Layout

The GE DS200TCQBG1A DS200TCQBG1AFB measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCQBG1A DS200TCQBG1AFB weighs approximately 0.53 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 DS200TCQBG1A DS200TCQBG1AFB provides six analog input channels. It accepts 4 to 20 mA signals from pressure and temperature transmitters. This board also delivers four analog output channels for actuator positioning. Each output generates 4 to 20 mA signals with 12-bit resolution. Consequently, it provides precise control of turbine valves and dampers. Accuracy stays within 0.2 percent of full scale at 25°C. The board includes built-in signal filtering for electromagnetic noise rejection. Optical isolation separates analog circuits from the digital backplane completely.

Installation and Diagnostic Features

You must insert the GE DS200TCQBG1A DS200TCQBG1AFB 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.
