Features:1. This module can convert 0-100% PWM digital signal into analog signal.2. The digital input signal can be from 0-100% PWM signal 3.3V level.3. The output analog signal can be 0-10V.4. Widely used in switching signal interface PLC, single IC or other industrial control board.5. The power supply has the reverse polarity of the protection function. Specification:1. Model: 3.3P-5VFuction: input 0-100% level PWM signal 3.3V, output voltage 0-10V2. PWM signal receiving frequency range: 100HZ-3KHZ (recommended 1-3KHZ)3. Insert the pitch pin on the 5V4. Analog voltage: below is the output voltage of 0-10V to illustrateAfter power on, when there is no input signal, the output is 0VPhen the first power on, calibration can be carried out: input the signal with a duty cycle of 50% and an amplitude of 3.3V into the DIN-i DIN+. The frequency is 1-3KHZ. Use a multimeter to measure the two AO and GND ports. Adjust the potentiometer on the board so that the multimeter display is 5.40V. This calibration of the appropriate relationship between the pulse signal and this module. The resolution of this module is 0.1V. The output current capability is 10MA. If the duty cycle percentage is inversely related to the voltage, you can check the low step active checkbox to set the PWM output pins in the mach3.5 software. Supply voltage: 15-30VDC (power supply requirement: gt; 100MA), 12V configurable6. Output power: about 10MA7. Mounting method: 4*M3Port screw hole:1. DIN+: positive PWM signal (for common cathode, connect it to PWM signal, for common anode, connect it to 3.3V signal terminal)2. DIN-: negative PWM signal (for common cathode, connect it to GND, common anode, connect it to PWM signal)3. 12-30V: positive power supply4. GND: Power Ground5. GND: Power Ground. It is connected to the ground of the power supply6. AO: Analog voltage output port (0-10V)Package List:1*PLC digital-to-analog module
