GE DS200UCIBG1AAA UC2000 Motherboard

الوصف

The GE DS200UCIBG1A UC2000 Motherboard is a crucial component within General Electric’s Mark V Speedtronic Turbine Control System.¹

Its primary role is to serve as the foundational backplane for the main processing and communication boards within the core control panel, specifically in the R Core (one of the three redundant cores—T, R, and S).²

⚙️ Board Function and Components

The DS200UCIBG1A, often referred to by its functional acronym UCIB, is the central hub for the control engine’s intelligence and interface.³

1. Host for Daughterboards⁴

The UCIB board does not contain the main turbine control processor itself; instead, it provides the connectors and infrastructure for mounting critical daughter cards:⁵

• LBC586P Daughterboard:⁶ This is the main CPU board (equipped with a Pentium-class processor) that executes the complex control sequencing and algorithms for the turbine. The LBC586P mounts directly onto the UCIB.⁷
• PANA (ARCNET No-LAN Driver Board): This board handles the high-speed ARCNET communication network, which is vital for the system’s Triple Modular Redundancy (TMR) voting scheme, allowing the T, R, and S cores to exchange data.⁸
• $\mu$GENI Boards: Connectors are available for mounting up to two ⁹$\mu$GENI (Micro Genius I/O) boards, which manage communications with field I/O devices.¹⁰

2. Signal Pre-Processing

The UCIB board contains its own onboard microprocessor (typically a 196 processor) to perform time-critical signal conditioning:¹¹

• It translates high-resolution pressure transducer signals received from the TCSA board (Fuel Skid Interface Board), specifically used for Dry Low Emissions (DLE) applications in gas turbines.¹²
• These pre-processed signals are then passed to the main LBC586P processor for use in the main control program.

3. Key Hardware Details

• Product Series: Mark V Speedtronic Turbine Control System.¹³
• Location: Installed in the R Core of the control panel (hence “R Core Motherboard”).¹⁴
• Revision: The trailing ‘A’ indicates the first functional revision of the base DS200UCIBG1 design.
• Diagnostics: Like other Mark V boards, it typically includes a block of LEDs for visual diagnostics, which flash in a sequence when the board is healthy or flash an error code if a fault is detected.
