I/O modules

The GE DS200LRPAG1P DS200LRPAG1PR1A execute logic and sequencing for GE Mark V turbine systems. These control cards manage protection, metering, and generator excitation functions. You can use either card for critical turbine control operations. The units provide high-speed processing for real-time loop closure.

Processing and Memory Specifications

The GE DS200LRPAG1P DS200LRPAG1PR1A execute one instruction in 0.2 microseconds. These control cards store 2 MB of turbine control logic in flash memory. You can rely on their 32-bit RISC processors for fast calculations. The units provide 512 KB of RAM for real-time data storage.

Physical Dimensions and Weight

Each control card weighs 0.28 kg for secure chassis mounting. The unit measures 185 mm long by 120 mm wide. Its PCB thickness reaches 1.6 mm with six internal copper layers. You can mount either card using four M3 screws through the designated holes.

Interface and Connection Points

Two 50-pin ribbon cable headers connect to the turbine backplane. One 20-pin header handles communication with I/O expansion boards. The GE DS200LRPAG1P DS200LRPAG1PR1A include a 4-pin power input connector. You will find eight LED indicators showing processor and communication status. Additionally, ten test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These control cards store minimal energy for temporary data retention. Four electrolytic capacitors provide 220 µF of total bulk storage. A supercapacitor maintains real-time clock for 72 hours during power loss. The cards 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 memory controllers and peripherals. Four static RAM chips provide high-speed data access for the CPU. You will find 128 resistors, 86 capacitors, and 12 integrated circuits on the board. The GE DS200LRPAG1P DS200LRPAG1PR1A include a watchdog timer for failsafe operation. A metal shield covers the processor section for electromagnetic compatibility.

Variant Equivalence and Use

The GE DS200LRPAG1PR1A 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 cards restores logic control to Mark V systems. Use GE DS200LRPAG1P DS200LRPAG1PR1A for turbine protection, excitation control, or sequencing applications. For best results, update the firmware to match your system requirement
