Features 【Product Features】: This module can convert the PWM digital signal to analog signal. Enter the digital signal can be a 3.3V level pwm signal. The output simulation signal can be 0-10V voltage. The power supply input has anti-connection protection functions. 【High Precision】: The range of power supply is wide, and the output voltage supports a lot of range, zero and full volume. The current signal sampling resistance uses a high -precision color ring resistance, high accuracy, small temperature drift, and high power. 【High Stability】: During the circuit signal transmission process, the voltage signal will weaken as the transmission distance increases. By -current transmission can avoid weakening signals. High stability, good linear, industrial grade. 【Safe and Easy to Use】: The voltage converter is protected by short circuit protection, anti -polar protection and overheating protection. 【Wide Application Range】: Signal interface switching widely used in PLC, single -chip microcomputer or other industrial control boards can be used for PLC and frequency conversion interfaces, or motion control cards and inverter interface supporting occasions.

Specification: 1. 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 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.
