The GE DS200FCSAG1A is a specialized circuit board known as a Current Sensing Interface or Current Sensing Feedback Board. It is a key component of the legacy GE Speedtronic Mark V series of industrial control systems, which are primarily used in the power generation industry for controlling turbines and static starters.
Key Features and Function
- Current Sensing: The primary function of this board is to measure and provide feedback on the electric current flowing through a circuit. It is used in conjunction with a Control Power Supply (CPS) and is typically installed in the Power Conversion Cabinet for Static Starters.
- Signal Monitoring: The board receives and processes signals related to current, which is essential for real-time monitoring, power management, and detecting faults within the system. It can detect abnormal current levels that may indicate a fault, triggering protective measures to prevent damage to the system.
- Control Power Supplies: The DS200FCSAG1A accepts and uses several voltage supplies from the CPS, including 5 VDC, 12 VDC, 15 VDC, and 24 VDC. These voltages are produced specifically for this board and the VME card rack.
- Closed-Loop Control: The board is often used in closed-loop control systems where the measured current is compared to a desired value. The feedback from the board is used to adjust system parameters to maintain the desired current level. This is a common application in motor control and power converters.
- Obsolete Status: As a component of the discontinued Mark V series, the DS200FCSAG1A is considered an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.
- Robust Design: The board is often conformal coated to protect it from environmental contaminants such as dust, moisture, and chemicals, ensuring its reliability in harsh industrial environments.
