GE DS200TCCBG1ANE Common Extended Analog IO Board

الوصف

The GE DS200TCCBG1ANE is a Common Extended Analog I/O Board that is a component of the GE Speedtronic Mark V Turbine Control System.

Its core function is to expand the system’s analog signal capacity by providing dedicated processing, scaling, and conditioning for a secondary group of analog inputs and outputs, particularly those related to temperature and current loops.

⚡ Function and Purpose

The DS200TCCBG1ANE board (functional acronym $\text{TCCB}$) serves as an I/O card within one of the Mark V’s control cores (R, S, or T). Its main roles include:

• Extended Analog I/O: It augments the primary analog I/O capabilities of the main control processor, allowing the system to interface with more field devices.
• $\text{RTD}$ Signal Conditioning: It contains the circuitry that supplies excitation to $\text{RTD}$ (Resistance Temperature Detector) sensors connected via the $\text{TBCB}$ (Terminal Board Common B) terminal board. It then processes and scales the $\text{RTD}$ input signals to provide accurate temperature readings to the main controller.
• Current Signal Processing: It provides the circuitry for handling common industrial signals like $\text{4-20 mA}$ and $\text{0-1 mA}$ analog current inputs.
• $\text{PT}$ and $\text{CT}$ Scaling: The board is also responsible for scaling and conditioning signals from $\text{PT}$ (Potential Transformer) and $\text{CT}$ (Current Transformer) inputs, which are crucial for monitoring electrical parameters on the turbine-generator.
