GE DS200UPLAG1ADC LAN Power Supply Card

الوصف

The GE DS200UPLAG1ADC LAN Power Supply Card is a printed circuit board (¹$\text{PCB}$) designed for the General Electric Mark V Speedtronic Gas Turbine Control System.²

Its primary role is to provide the regulated power supply necessary for the ³$\text{LAN}$ (Local Area Network) communication circuits within the turbine control module.⁴

⚙️ Function and Application

• Core Function (⁵$\text{UPLA}$): ⁶$\text{UPLA}$ stands for ⁷$\text{LAN}$ Power Supply Circuit.⁸ The card’s job is to ensure a clean, stable, and consistent ⁹$\text{DC}$ voltage supply to the communication electronics that facilitate data exchange between the Mark V’s control processors (¹⁰$\text{R}$, ¹¹$\text{S}$, ¹²$\text{T}$).¹³
• System Criticality: In the Mark V’s Triple Modular Redundancy ($\text{TMR}$) architecture, reliable communication is vital for the processors to vote on critical control and protection signals (2-out-of-3 voting). The ¹⁴$\text{UPLA}$ card is thus essential for maintaining the fault tolerance and reliability of the entire system.¹⁵
• Design: The board incorporates voltage regulation circuits and overcurrent protection to safeguard the connected ¹⁶$\text{LAN}$ circuits from power fluctuations or surges.¹⁷

Important Replacement Note

Like all configurable GE control cards, the $\text{DS200UPLAG1ADC}$ likely contains jumpers or $\text{DIP}$ switches that must be set to match the configuration of the old board upon replacement. Failing to do so will result in an incorrect “personality” and system malfunction.
