Voltage to Frequency Module
This is a linear conversion module, which converts the input voltage signal into the corresponding output frequency after processing by the internal chip.
There are two choices of input voltage range and two choices of output frequency.
Module parameters
1. Supply voltage: 9V to 24V
2. Input voltage range: 0.00V to 5.00V / 0.00V to 10.00V
3. Signal output frequency range: 0Hz ～ 1KHz / 0Hz ～ 10KHz
4.signalOutput duty cycle range: 50%
5. Input method: J1 pad on the circuit board: open circuit (0 ～ 5V); short connection (0 ～ 10V) is open circuit by default.
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. Driving mode: open collector NPN drive, maximum current 200MA, external voltage range 1 ～ 30V.
8. Application: remote data acquisition and control equipment;
9. Size: (length) 26mm * (width) 23mm * (height) 10mm
10. Module interface:
24V: positive power connector (9V to 24V).
G: Power ground interface.
IN: Signal input positive connector.
G: signal input negative connector.
OUT: Signal output interface (0Hz ~ 1KHz / 0Hz ~ 10KHz).
G: Power ground interface.
Input voltage selection: J1 pad
Open circuit: Input (0.00V ~ 5.00V) output corresponding frequency pulse signal.
Short circuit: input (0.00V ~ 10.00V) to output pulse signal of corresponding frequency.
Output frequency selection: S2 pad
Open circuit: Output 0 ～ 1KHz pulse signal.
Short circuit: output 0 ～ 10KHz pulse signal.
