The GE DS200TVCOG1A is an Isolated Voltage Feedback Board manufactured by General Electric, primarily used in the Mark V Speedtronic Turbine Control System or related GE Drive Control Systems.1
Its essential function is to safely and accurately measure voltage in a system and provide that reading back to the main controller while maintaining electrical isolation.2
⚡ Core Function: Isolated Voltage Feedback
The DS200TVCOG1A board performs a critical safety and control function by isolating high-voltage circuits from the sensitive, low-voltage control electronics.3
- Isolation Barrier: The board is designed to maintain a high level of electrical isolation between the high-voltage input side (the voltage source being measured, often in a drive or power supply) and the low-voltage output side (the control system).4 This prevents potentially damaging voltages or electrical noise from transferring to the main control processors.5
- Voltage Sensing: It accurately senses the output voltage of a power supply or drive.6
- Feedback Signal: It conditions and converts the measured voltage into an isolated, stable feedback signal that the Mark V control system uses to regulate and stabilize the output voltage.7 This is essential for maintaining precise control in industrial applications like motor control or power supply regulation.
