This module is a frequency conversion pulse signal and voltage conversion module. The voltage-to-frequency pulse signal can generate different frequency modules according to the input voltage level. The frequency to analog voltage signal can convert 0-1KHZ frequency to 0-10V voltage output, and adjust the frequency to change the output voltage.
Product Parameter:
Frequency to voltage module:
Working voltage: 13.5V-30V
Input frequency range: 0-1KHz
Output voltage range: 0-10V
Output voltage: adjustable (calibrate the relationship between frequency and voltage through a potentiometer)
Precautions:
Input different frequencies and output corresponding voltages.
The input pulse level is 5V, 12V, 24V and can be directly input without series resistance. But the input signal frequency should be maintained for more than 0.5 seconds
The output voltage can be fine-tuned. The relationship between frequency and voltage can be calibrated by a potentiometer.
The signal input terminal uses optical coupling isolation to ensure anti-interference ability.
If need to match PLC, support NPN type. There must be a ground wire.
If it needs to be equipped with an encoder, the encoder must be rotated at a constant speed for more than 0.5 seconds.
F/V conversion module, response time is about 0.3-0.5 seconds. If the frequency is adjusted at one time, a certain response time is required.
Voltage to frequency module:
Working voltage: 13.5V-30V
Input controllable voltage range: 0-10V
Output frequency range: 0-10KHZ
Precautions:
Input voltage, output frequency signal
The output signal can be fine-tuned, and the potentiometer can be adjusted to calibrate the correspondence between voltage and frequency. The output of this module can be supplied to the driver as a pulse signal. When used with the driver, the common anode wiring is used. The related wiring is OC-OUT, which is connected to the driver's PUL- or PUL. 12-30, connected to the drive PUL+ or public terminal +5V, (a 330R resistor is required for 12V power supply, a 2.7K resistor is required for 13-24V power supply for current limiting)
