Voltage to Frequency Module
This is a linear conversion module, which converts the input voltage signal into the corresponding output frequency through internal chip processing.
There are two input voltage range options, and two output frequency options.
Module parameters
1. Power supply voltage: 9V ~ 24V
2. Input voltage range: 0.00V ~ 5.00V / 0.00V ~ 10.00V
3. Signal output frequency range: 0Hz～1KHz/0Hz～10KHz
4. Signal output duty cycle range: 50%
5. Input mode: J1 pad on the circuit board: open circuit (0~5V); short circuit (0~10V) default is open circuit.
6. Output mode: S1 pad is not used, S2 pad on the circuit board: open circuit (0 ~ 1KHz); short circuit (0 ~ 10KHz), the default is open circuit.
7. Drive mode: open-collector NPN drive, the maximum current is 200MA, and the external voltage range is 1~30V.
8. Scope of application: remote data acquisition and control equipment;
9. Dimensions: (length) 26mm * (width) 23mm * (height) 10mm
10. Module interface:
24V: Positive port of power supply (9V ~ 24V).
G: Power ground interface.
IN: Signal input positive connector.
G: Signal input negative terminal.
OUT: Signal output interface (0Hz～1KHz/0Hz～10KHz).
G: Power ground interface.
Input voltage selection: J1 pad
Open circuit: Input (0.00V ~ 5.00V) and output corresponding frequency pulse signal.
Short circuit: Input (0.00V ~ 10.00V) output corresponding frequency pulse signal.
Output frequency selection: S2 pad
Open circuit: output 0~1KHz pulse signal.
Short circuit: output 0~10KHz pulse signal.
