I/O modules

The GE DS3810MMBB1A1A serves as a dedicated memory board for the Mark V series. This module stores critical turbine control parameters and logic programs. You will find this board in gas, steam, and wind turbine applications. It integrates seamlessly with the Mark V speedtronic system.

Manufacturer: General Electric
Series: Mark V Speedtronic
Category: Memory Board (Non-Volatile Storage)

Physical Specifications

The GE DS3810MMBB1A1A measures 10.5 inches in length. Its width reaches 4.2 inches for standard rack mounting. The board thickness sits at 1.8 inches including components. This compact design fits into any Mark V card slot. The total weight comes to approximately 0.45 kilograms.

Technical Parameters and Storage Capacity

This memory board uses high-reliability EPROM technology for data retention. It stores up to 512KB of user program code. Additionally, the board holds 128KB of configuration parameters. A backup capacitor array provides temporary power during module swaps. This energy storage lasts up to 72 hours without main power.

Interface and Connectivity

The GE DS3810MMBB1A1A connects through a 64-pin edge connector. This interface links directly to the Mark V CPU backplane. Data transfers occur at 10 MB per second maximum. The board includes status LEDs for power and activity monitoring. Therefore, you can diagnose issues without special tools.

Component Layout and Construction

This memory board features a four-layer PCB for noise reduction. It contains twelve EPROM chips in dual in-line packages. Four surface-mount capacitors form the energy storage array. Two jumpers allow configuration for different turbine models. All components meet industrial temperature ratings from -30°C to +65°C.

Energy Storage and Data Retention

The GE DS3810MMBB1A1A includes a supercapacitor backup system. This energy storage maintains memory contents during power interruptions. You get 72 hours of data retention without external power. Consequently, short maintenance outages do not erase your programs. The capacitors recharge automatically when the system powers up again.

Integration and Compatibility

Use the GE DS3810MMBB1A1A with any Mark V CPU module. It works alongside DS3810 series I/O and communication boards.
