GE IC3600SVFA1 VOLTAGE-TO-FREQ-CONV

الوصف

The GE part number IC3600SVFA1 is a Voltage-to-Frequency Converter Card. This electronic circuit board is a component of GE’s legacy Speedtronic Mark I and Mark II series of turbine control systems. Its primary function is to convert a variable DC voltage signal into a proportional frequency signal.

Function and Key Features

A Voltage-to-Frequency Converter (VFC) is a type of analog-to-digital converter. It takes an analog input voltage and generates a series of pulses (a frequency) whose rate is directly proportional to the magnitude of the input voltage. This conversion is crucial in many industrial control systems because frequency signals are more resistant to electrical noise than analog voltage signals.

• Signal Conversion: The card receives a DC voltage input that represents a specific parameter, such as turbine speed, temperature, or pressure. It then generates a corresponding output frequency.
• Noise Immunity: By converting the signal from an analog voltage to a digital frequency, the card makes the signal more robust and less susceptible to electrical interference. This is particularly important in the electrically noisy environment of a power plant.
• System Integration: The converted frequency signal is then used by other digital or counting circuits in the control system. For example, a frequency signal representing turbine speed can be used by a digital counter to provide an accurate speed readout or to trigger an overspeed trip.
• Robust Design: Like all GE industrial control boards, it’s built to withstand the harsh conditions of a power plant, including vibrations, temperature fluctuations, and electromagnetic interference.

Applications

The IC3600SVFA1 is a legacy component, so it is primarily used in power generation facilities that still operate GE’s older Mark I and Mark II turbine control systems. It is an essential component for:

• Speed Sensing: Converting a speed-proportional voltage from a tachometer into a frequency signal for accurate speed monitoring and control.
• Instrumentation: Converting various analog sensor outputs into more reliable frequency signals for data acquisition and display.
