I/O modules

The GE DS200TCCBG3B DS200TCCBG3BCB provides analog I/O processing for Mark V TC2000 turbine controls. You can install this board into the main turbine control cabinet. It interfaces with field sensors and control actuators. This board suits gas and steam turbine process control applications.

Technical Specifications and Hardware Layout

The GE DS200TCCBG3B DS200TCCBG3BCB measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCCBG3B DS200TCCBG3BCB weighs approximately 0.44 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 Specifications and Performance

The GE DS200TCCBG3B DS200TCCBG3BCB provides six analog input channels. It accepts 4 to 20 mA signals from pressure and temperature sensors. This board also delivers six analog output channels for actuator control. 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 noise rejection. Optical isolation separates analog circuits from the digital backplane completely.

Installation and Diagnostic Features

You must insert the GE DS200TCCBG3B DS200TCCBG3BCB 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.
