Physical Construction and Component Layout
This DS200UCIBG1A DS200UCIBG1AAB UC2000 motherboard measures 12.5 inches in length. Its width reaches 8.3 inches with a thickness of 1.9 inches. The total weight comes to approximately 2.85 pounds. Manufacturers placed 486 discrete components on this eight-layer PCB. These components include a CPU socket, memory slots, chipset, clock generator, and bus interface logic. Both DS200UCIBG1A and DS200UCIBG1AAB share the same motherboard architecture.
Processor Support and Memory Configuration
DS200UCIBG1A DS200UCIBG1AAB accommodates a 32-bit PGA processor for main computing. The clock generator selects 25, 33, or 50 MHz operating speeds. Two SIMM memory slots accept standard RAM modules for system memory. One EPROM socket holds firmware for boot operations. Onboard cache provides 256 KB of SRAM for faster data access. CMOS RAM stores 128 bytes of configuration with battery backup. A 3V lithium battery keeps CMOS and RTC data for five years.
Expansion Capability and I/O Ports
DS200UCIBG1A DS200UCIBG1AAB features four ISA expansion slots for legacy cards. Two additional PCI slots support higher-speed peripheral devices. A 96-pin DIN connector interfaces directly with the Multibus backplane. Two RS-232 serial ports connect to modems or terminals. One parallel port supports printers or external storage. One PS/2 port accepts a standard keyboard for operator input.
Energy Storage and Application Use
DS200UCIBG1A DS200UCIBG1AAB integrates twelve 470µF capacitors for bulk power storage. Eight additional 100µF capacitors filter high-frequency noise on all rails. The board draws 1.2 amps at 5V and 0.2 amps at ±12V. You will find this motherboard in GE UC2000 industrial computer systems. It serves as the main processing platform for turbine controls. The board operates reliably from 0°C to 55°C ambient temperature. For example, it hosts data acquisition or HMI applications. Therefore, this UC2000 motherboard provides a flexible computing platform for GE automation systems.
