LC-LM358-PWM2V

Overview
LC PWM turn voltage module LC-LM358-PWM2V can convert PWM digital signal into 0 to 10 v analog signals.Can be used in the PLC or other industrial panel switch signal interface.By adjusting the PWM duty ratios to adjust output voltage.Module size is small, easy to apply in different places.
 
Function features
1.MCU embedded technology.
2.Easy to operate, can pass to fine-tuning potentiometer.
3.Through the short circuit choose PWM signal input level range.
4.Module is small, portable and easy to use.

Technical parameters
1.Module working voltage: DC 12V - 30V(power requirement: more than 100 mA)
2.PWM signal receiving frequency range: 1 KHZ - 3 KHZ

PWM signal input level range:
Fengfeng value of 4.5V to 10V level, jump needle at 5V.The class level signal mainly for conventional industrial control CARDS (e.g., MACH3 boards), 5V CPU interface;
Fengfeng value between 12 and 24V level, jump needle at 24V.The class level signal mainly for conventional PLC interface.
PWM conversion range: 0% - 100% PWM conversion  0 to 10V
Permissible error: 5%
 
Introductions
VCC: work power 12V - 30V
GND: working power
PWM: input PWM signal positive pole
GND: the input signal is negative end
VOUT: 0 to 10V output voltage
GND: output voltage

Instructions: after power on, there is no input signal, the output is 0V.Electricity for the first time, it's best to do a calibration debugging: find a 50% duty cycle of the access to the PWM signal, GND, corresponding to the relative amplitude jump needle.Frequency in the 1 KHZ - 3 KHZ, VOUT is measured with a multimeter, GND two ports, the table displays at around 5V, adjust the potentiometer on the board, make says in 5.00V on the multimeter. The calibration is your pulse signal and the corresponding relation of the module.When the frequency changes, there may be offset, the corresponding relationship needs to be calibrated.
Output voltage can be adjusted by adjusting the duty ratios.
Precision could be controlled by adjusting the potentiometer.
