  • ►【Product introduction】: This series of products are PWM and pulse signal generators. There are PWM mode and pulse mode. Only one mode can be used at a time, but the two modes can be switched at any time.
  • ►【Product Specifications】: Working voltage DC 3.3-30V; frequency range 1Hz-150kHz; duty ratio range 0-100%; number of pulse 1-9999 or infinite.Signal carrying capacity: <30mA; output signal secondary value: the secondary value is equal to the supply voltage.
  • ►【Features】:Dual mode: the function signal generator has 2 modes, PWM mode (default) & pulse mode.Easy to operate: the signal generator can control start or stop, it can also connect the external switch to control the output signal ON/OFF.
  • ►【Operation explanation】: 1. There is an output waveform when powered on; 2. Waveform amplitude = power supply voltage; 3. When the number of output pulses reaches the set value, the output will be automatically stopped, and 'OUT' will disappear; 4. Press the ON key to control the presence or absence of the waveform, the disappearance of OUT means that there is no output waveform, and the output is 0; 5. Power on and restart or ON key to turn on the output, and recalculate the number of pulses;
  • ►【Application scenarios】: It is used to generate square wave and rectangular wave signals to control DC motor or stepper motor driver; it is used for servo motor, stepper motor, electric gripper, replace PLC pulse, etc.


Product Description

product

  • Duty cycle range: 0-100%, 1% stepping.
  • Number of pulses: 1-9999, or infinite (display '----'stands for infinity).
  • Delay output time: 0.000s-9999s, the minimum can be set 1ms.
  • positive and negative pulse width length: 0.000s-9999s, the minimum can be set 1ms.
  • Output signal amplitude: amplitude is equal to the supply voltage.
  • PWM mode - frequency (continuous), duty cycle. Note that the number of pulses cannot be set in this mode, and the pulse is always sent;
  • PULSE mode - positive pulse width time, negative pulse width time, delay start time, and number of pulses are adjustable.

The faceplate on these is not rigid, but the signal is quite accurate and the electronics seem up to the task.

Worked perfect to control a treadmill motor by pwm 20hrtz signal to board then duty cycle controls speed. Very happy

This thing does a good enough job. If you need a very clean signal, consider other options. For me, it worked fine.

While it does produce a square wave of the desired frequency, the duty cycle is invented and the max amplitude is just under 2v. The v- and v+ pins only offset the signal, not increase the amplitude of the signal.

I used it to control a treadmill DC motor on my home made 72" belt sander it worked as intended. Great price.
