GE DS200UCIBG3A DS200UCIBG3AAB 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 DS200UCIBG3A and DS200UCIBG3AAB versions share identical backplane routing. These motherboards use six-layer PCB construction with dedicated power and ground planes. Consequently, the GE DS200UCIBG3A DS200UCIBG3AAB 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 DS200UCIBG3A DS200UCIBG3AAB distributes communication signals across a VME parallel bus. Therefore, it simplifies system integration for GE turbine control upgrades.
