Features: 1.This module can convert 0~100% PWM digital signal to analog signal. 2. The input digital signal is 0-100% PWM signal at 3.3V level. 3. The output analog signal is 0-10V voltage. 4. Widely used in PLC, single chip or other industrial control board signal interface switching. 5. Power supply has reverse polarity protection Specification: 1. Model: 3.3P-5V Function: 3.3V level input 0-100% PWM signal, output 0-10V voltage 2. PWM signal reception frequency range: 100HZ-3KHZ (1-3KHZ) Insert jump pin at 3.5V 4. Analog voltage output: below is 0-10V output voltage for explanation. If there is no input signal after power-on, the output is 0V. When the first power is on, it can perform calibration. The resolution of this module is 0.1V. The output current capacity is 10MA. If the duty cycle percentage is opposite to the voltage, you can turn on the STEP LOW, ACTIVE check box and set the pin for PWM output with the MACH3 software. Input voltage: 15-30VDC (Power requirement:> 100MA), customizable 12V 6. Output power: about 10MA 7. Installation method: 4 * M3 screw hole port: 1. DIN+: PWM signal positive (connect to PWM signal for common casode, and for common anodes connect to 3.3V to the signal terminal) 2. Negative (Common Barrel) GND for sword, connect to GND, for common anodes, connect to PWM signal.) 3. 12-30V: power supply plus 4. GND: power ground 5. AO: Analog voltage (0-10V) output port Package list: 1 * Digital analog PLC module
