Key Technical Specifications
This GE DS200UCIBG1A DS200UCIBG1AAA motherboard operates from a 24V DC power supply. It provides 8 VME slots for UC2000 control system modules. The unit measures 30 cm in length, 22 cm in width, and 5 cm in height. Its total weight reaches 1.2 kg without any packaging materials.
The GE DS200UCIBG1A DS200UCIBG1AAA includes 8 DIN 41612 connectors for module insertion. Additionally, it features one 50-pin ribbon header for external system interface. A single 6-pin terminal block connects the main DC power input. The motherboard contains 8 connectors, 4 bus bars, 2 voltage planes, 16 decoupling capacitors, and 8 status LEDs.

GE DS200UCIBG1A DS200UCIBG1AAA distributes 160 µF total capacitance across all 8 slots. Each slot receives 20 µF local decoupling for stable operation. This arrangement filters high-frequency noise from the VME bus. Therefore, the board ensures clean power delivery to every plug-in module.
Design and Integration
Both the GE DS200UCIBG1A and DS200UCIBG1AAA versions share identical backplane routing. These motherboards use six-layer PCB construction with dedicated power and ground planes. Consequently, the GE DS200UCIBG1A DS200UCIBG1AAA operates reliably from -10°C to +60°C ambient temperature.
For installation, you need M4 screws for the eight mounting holes. The motherboard draws 20 mA typical current for LED indicators only. Each slot can deliver up to 10A continuous current to its module. We recommend using 10 AWG wire for the main power input connection.
Practical Application
This UC2000 motherboard serves as the mechanical and electrical backbone for a UC2000 control rack. It hosts processor, I/O, and communication boards in one chassis. The GE DS200UCIBG1A DS200UCIBG1AAA distributes communication signals across a VME parallel bus. Therefore, it simplifies system integration for GE turbine control upgrades.
