1. PWM signal generator, square rectangular signal generator
2. Used to generate square rectangular signals for controlling DC motor or stepper motor driver; used for servo motor, stepping motor, electric gripper, replacing PLC pulse, etc.
3. The supporting driver realizes dimming, speed regulation, control of solenoid , etc., but can not directly drive the load of the electric motor solenoid .
1. Two modes can be selected
PWM mode – frequency (continuous), duty cycle, pulse number adjustable;
PULSE pulse mode – positive pulse width time, negative pulse width time, delay start time, and the number of pulses are adjustable.
2. With start and stop button, can control the output and stop of the signal

5. Delay output time:0.000s-9999s, the can be set 1ms
6. Positive and negative pulse width length:0.000s-9999s, the can be set 1ms
7. Signal loading capacity:less than 30mA
8. Output signal amplitude:amplitude is equal to the supply voltage
9. Product size:60 x 32 x 10mm
10. Product Weight:18g

PWM mode (display has ‘%’ for PWM mode)
1. The factory default mode is PWM mode, FREQ+ and FREQ-key set frequency, DUTY+ and DUTY-button set duty cycle; short press STOP button control signal output or stop, stop output is 0, the screen displays “OUT” mark as There is output, otherwise it stops output; the default factory frequency is 1KHZ and the duty cycle is 50%.
If you want to switch to PULSE pulse mode, long-press the SET button (more than 6 seconds), do not release, you will see the screen change, ‘%’ disappears, it is PULSE mode.
2. PULSE pulse mode (No ‘%’ on the right side of the display is displayed in PULSE mode)
The P+ and P- buttons set the positive pulse width time, the LCD screen shows up, the N+ and N- buttons set the negative pulse width time, the LCD screen displays downwards, the unit is seconds; short press the STOP button to control the signal output or stop, stop output It is 0, the screen displays “OUT” mark as output, otherwise it stops output; the default factory positive pulse width is 0.5 second, and the negative pulse width is 0.5 second.
Pulse number and delay time setting – In PULSE mode, press and hold the SET button for 2 seconds and then release, enter the pulse number and delay time setting interface, the screen displays SET, it will be turned off and cleared after entering. Output pulse; P+ and P- buttons set delay time, N+ and N- buttons set pulse number, factory default delay time is 0 seconds, pulse number is infinite (display —-); Press the button for 2 seconds, automatically return to the pulse interface, press the STOP button, after the delay setting time, start to send the set number of pulses, if the number of pulses is sent, it will automatically output 0, if the period is not sent, press the STOP button. The output pulse will be turned off and cleared, and the number of pulses set will be issued each time it is started.
Application Operation Examples
1. PWM output 20KHZ, 60% duty cycle:Select PWM mode, the frequency is set to 20.00, and the duty ratio is set to 060%.
2. The output is turned on for 0.6 seconds and turned off for 0.2 seconds. Infinite loop:select PULSE mode, the positive pulse width is set to 0.600, the negative pulse width is set to 0.200, the delay time is set to 0.000, and the number of pulses is set to — -.
3. Power on or press the start button, delay 5 seconds, then the output is turned on for 0.6 seconds, off 0.2 seconds, infinite loop:select PULSE mode, positive pulse width is set to 0.600, negative pulse width is set to 0.200, delay The time is set to 5.000 and the number of pulses is set to —-.
4. Power on or press the start button, delay 5 seconds, then output high level 10ms low level 10ms pulse 100:select PULSE mode, positive pulse width is set to 0.010, negative pulse width is set to 0.010, delay The time is set to 5.000 and the number of pulses is set to 0100.
5. Power-on delay for 10 seconds, then permanently output signal:select PULSE mode, the positive pulse width is set to a number greater than 0, the negative pulse width is set to 0, the delay time is set to 10.00 seconds, and the pulse number is infinite. (—-).
