I/O modules

The GE DS200UCPBG6A DS200UCPBG6ADA serve as the main processing units for GE Mark V turbine systems. These PC processor boards execute all turbine control logic and protection algorithms. You can use either board for generator excitation, speed control, and sequencing tasks. The units provide high-speed computation for real-time turbine management.

Processing and Memory Specifications

The GE DS200UCPBG6A DS200UCPBG6ADA execute one instruction in 0.1 microseconds. These PC processor boards store 4 MB of turbine control logic in flash memory. You can rely on their 66 MHz processors for fast loop closure. The units provide 2 MB of RAM for real-time data storage.

Physical Dimensions and Weight

Each PC processor board weighs 0.38 kg for secure chassis mounting. The unit measures 235 mm long by 152 mm wide. Its PCB thickness reaches 1.6 mm with six internal copper layers. You can mount either board using four M4 screws through the designated holes.

Interface and Connection Points

Four 50-pin ribbon cable headers connect to I/O and communication boards. One 20-pin header handles connection to the turbine backplane. The GE DS200UCPBG6A DS200UCPBG6ADA include a 4-pin power input connector for DC supplies. You will find eight LED indicators showing processor and system status. Additionally, twelve test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These PC processor boards store minimal energy for temporary data retention. Six electrolytic capacitors provide 330 µF of total bulk storage. A supercapacitor maintains real-time clock for 100 hours during power loss. The boards include no replaceable battery for program memory. An onboard EEPROM retains configuration data permanently without power.

Component Layout and Construction

The main processor chip includes integrated floating-point math capabilities. Eight static RAM chips provide high-speed data access for the CPU. You will find 168 resistors, 96 capacitors, and 18 integrated circuits on the board. The GE DS200UCPBG6A DS200UCPBG6ADA include a watchdog timer for failsafe operation. A metal shield covers the processor section for electromagnetic compatibility.

Variant Equivalence and Use

The GE DS200UCPBG6ADA represents a functional equivalent or later revision. Both versions share identical dimensions, connectors, and mounting hole locations. You can substitute one for the other without hardware modifications. Transitioning to these boards restores main CPU functionality to Mark V systems. Use GE DS200UCPBG6A DS200UCPBG6ADA for turbine control in power generation applications. For best results, update the firmware to match your system requirements before installation.
