4. Functionality
The MDF1106 operates by converting an input signal’s frequency into a proportional DC voltage. The input signal—whether square, triangular, or sinusoidal—is fed into the converter’s input stage, which detects the frequency of the waveform. The internal circuitry then processes this frequency information and generates a corresponding analog voltage output that scales linearly with the input frequency.

For example, an input frequency of 0 Hz corresponds to an output of 0 V, while an input of 20 kHz corresponds to an output of 5 V. Intermediate frequencies produce proportionally intermediate voltages. This linear relationship allows the MDF1106 to serve as a precise transducer for frequency-based measurements.

Typical Use Cases and Applications:
- Rotational Speed Measurement: Converts pulse or frequency signals from tachometers or encoders into voltage signals for analog monitoring or control.
- Flow Measurement: Used with flow sensors that output frequency signals proportional to flow rate, enabling analog representation of flow.
- Signal Conditioning: Acts as an interface between frequency-based sensors and analog input devices such as PLCs, controllers, or data acquisition systems.
- Automation and Control Systems: Provides real-time analog feedback proportional to frequency-based process variables.
- Laboratory Instrumentation: Used in test setups requiring frequency-to-voltage conversion for analysis or calibration.

Compatibility:
The MDF1106 is compatible with a wide range of signal sources, including magnetic pickups, optical sensors, and electronic pulse generators. Its 0–5 V output is suitable for direct connection to analog input channels of PLCs, microcontrollers, and measurement instruments.
