1. Used to generate square wave rectangular wave signals for controlling DC motors or stepper motor drivers; used for servo motors, stepper motors, electric grippers, instead of PLC pulses, etc.2. The matching driver realizes dimming, speed control, solenoid valve control, etc., but it cannot directly drive loads such as electric lamp motor solenoid valves3. Two modes can be selected:- PWM mode a frequency (continuous) duty cycle. Note that the number of pulses cannot be set in this mode, and pulses are always sent;- PULSE pulse mode one positive pulse width time, negative pulse width time, delay start time, pulse number are adjustable.5. With start and stop button, you can also connect an external switch to control the output signal ON/OFF.6. Wide voltage input 3.3-30V, with anti-reverse connection protection.7. The 5.08mm screw terminal is convenient for wiring, with a shell8. Working voltage: 3.3~30V, with anti-reverse connection protection9. Frequency range: 1Hz~150KHz, accuracy is about 1%10. Duty cycle range: 0-100%, 1% step11. Number of pulses: 1-9999, or infinite12. Delayed output time: 0.000s-9999s, the minimum can be set to 1ms13. Positive and negative pulse width length: 0.000s-9999s, the minimum can be set to 1ms14. Signal carrying capacity: less than 30mA15. Output signal amplitude: the amplitude is equal to the supply voltage16. Product size: 79mm x 43mm x 30mm17. Product weight: 40g
