Package contents:
Pack of 3 PWM to voltage module.
Module operating voltage: DC 12V-30V (power requirement: more than 100mA)
PWM signal reception frequency range: 1KHZ - 3KHZ;
PWM signal input level range:
Fengfeng value from 4.5V to 10V level, jump needle at 5V. The class level signal mainly for conventional industrial control cards (e.g. MACH3 cards), 5V CPU interface;
Fengfeng value between 12 and 24 V, jump needle at 24 V. The class level signal mainly for conventional SPS interfaces.
PWM conversion range: 0% - 100% PWM conversion 0 to 10V. Permissible error: 5%.
VCC: working power 12V-30V
GND: working performance
PWM: positive pole of input PWM signal
GND: The input signal is negative.
VOUT: 0 to 10V output voltage
GND: Output Voltage
Instructions: after switching on, there is no input signal, the output is 0V. Current for the first time, it is best to perform calibration debugging: find a 50% duty ratio of access to the PWM signal, GND, according to the relative ampl. itudensprungneedneedle. . Frequency in the range 1KHZ - 3KHZ, VOUT is measured with a multimeter, GND two ports, the table shows about 5V, set the potentiometer on the board, set 5.00V on the multimeter. The calibration is your pulse signal and the corresponding ratio of the module. If the frequency changes, there may be an offset, the corresponding ratio must be calibrated.
The output voltage can be adjusted by adjusting the duty ratios.
