GE IC3600QOXC19 Overspeed Sensor Card

الوصف

The GE IC3600QOXC19 is an Overspeed Sensor Card for the Mark I/II Speedtronic series. It’s a critical safety circuit board that processes signals from a speed sensor to detect when a turbine is running at or above a dangerous overspeed condition.

Technical Breakdown 🧠

An overspeed sensor card is a specialized input module that takes a signal from a magnetic or proximity sensor (often a “pickup”) mounted near a toothed wheel on the turbine shaft. As the wheel spins, the sensor generates a series of pulses. The IC3600QOXC19 card’s primary function is to:

• Measure Frequency: The card precisely measures the frequency of these pulses, which is directly proportional to the turbine’s rotational speed.
• Compare to Setpoint: It continuously compares the measured speed against a pre-programmed overspeed trip setpoint.
• Initiate Trip: If the measured speed exceeds the setpoint, the card’s hard-wired logic triggers an immediate and irreversible trip signal, which shuts down the turbine to prevent a catastrophic failure.

This hard-wired safety logic is independent of the main control processor, making it a critical last line of defense against overspeed events.

Applications 🏭

The IC3600QOXC19 is a foundational safety component in GE Mark I/II turbine control panels for:

• Overspeed Protection: Acting as a primary safety device to prevent dangerous turbine overspeed.
• Safety System Redundancy: Providing a robust, hard-wired backup to the main control system’s software-based speed control.
• Catastrophic Failure Prevention: Protecting the turbine and surrounding equipment from mechanical damage due to excessive speed.
