Model: 3.3P-5V Function: Input 0-100% PWM signal of 3.3V level, output 0-10V voltage 2. PWM Signal Receive Frequency Range: 100HZ-3KHZ (1-3KHZ is recommended) 3. Insert the jump pin at 5V 4. Analog Voltage Output: The following is the output voltage of 0-10V to illustrate After power-on, when there is no input signal, the output is 0V For the first power-up, a calibration can be done: Input a signal with 50% duty cycle and 3.3V amplitude to DIN- and DIN+. The frequency is 1-3KHZ. Use a multimeter to measure two ports of AO and GND. Adjust the potentiometer on the board to make the multimeter display 5.40V. This calibrate the corresponding relation between pulse signal and this module. The resolution of this module is 0.1V. The output current capability is 10MA. If the percentage of the duty cycle is inversely related to the voltage, you can check the check box of STEP LOW, ACTIVE to set the pins of PWM output in the MACH3 software. 5.
