4.Work Mode:

1>.PWM Mode:Frequency,Duty cycle

1.1>.It is PWM mode when display ‘%’.

1.2>.The factory default mode is PWM mode.

1.3>.on FREQ+ and FREQ- are used to setting output frequency.User can short pre by set value in minimum unit or keep pre to continuous setting. Frequency range is 1Hz to 150KHz.

1.4>.on DUTY+ and DUTY- are used to setting output duty cycle for frequency.User can short pre by set value in minimum unit or keep pre to continuous setting. Duty cycle range is 0.00% to 100%.

1.5>.Short pre on ‘STOP’ to enabled or disabled output.It is enabled output when display symbol ‘OUT’ on left.It is disabled output if no display symbol ‘OUT’ and module will output 0V.

1.6>.The default factory frequency is 1KHz and the duty cycle is 50%.

1.7>.Switch work mode:Keep pre on ‘SET’ about 6 second.The it is enter into PULSE mode if symbol ‘%’ disappear on right.

2>.PULSE Mode:Pulse width,Delay,Pulse number

2.1>.It is PWM mode without display symbol ‘%’.

2.2>.on P+ and P- are used to set time for positive pulse width.Displayed on the first line.Set time range is 0.000s~9999s.

2.3>.on N+ and N- are used to set time for negative pulse width time.Displayed on the second line.Set time range is 0.000s~9999s.

2.4>.Short pre on ‘STOP’ to enabled or disabled output.It is enabled output when display symbol ‘OUT’ on left.It is disabled output if no display symbol ‘OUT’ and module will output 0V.

2.5>.The default factory positive pulse width is 0.5 seconds, and the negative pulse width is 0.5 seconds.

2.6>.Long pre on ‘SET’ for 2 seconds to enter into set the number of pulses and delay time.Screen will display symbol ‘SET’ at lower left corner.Note:Once in this mode,the output will be disabled and output pulse will be cleared.

2.7>.on P+ and P- are used to set delay time.Set time range is 0.000s~9999s.

2.8>.on N+ and N- are used set the number of pulses.Set range is 1~9999 or Infinite.

2.9>.The factory default delay time is 0 seconds, and the number of pulses is infinite (display ‘----’).

2.10>.Automatic return to pulse interface by pre on ‘SET’ for 2 seconds.

2.11>.Short pre on ‘STOP’ to delay the set time and start output the set number of pulses.

2.12>.It will automatically output 0V if the number of pulses is sent.The output will be disabled and clear pulse numbers if pre on ‘STOP’ during output.

2.13>.The number of set pulses is output each time when module power on.

5.Practical application:

1>.PWM output 20KHz,60% : Select PWM mode.Set frequency to 20.00 and duty cycle to 060%.

2>.Output turn ON 0.6s,OFF 0.2s,infinite loop : Select PULSE mode.Set positive pulse width to 0.600 and negative pulse width to 0.200.Delay time to 0.000.Number of pulses to ‘----’.

3>.Delay 5s after power ON or pre ‘STOP’ on.Then output turn ON 0.6s,OFF 0.2s,infinite loop : Select PULSE mode.Set positive pulse width to 0.600 and negative pulse width to 0.200.Delay time to 5.000.Number of pulses to ‘----’.

4>.Delay 5s after power ON or pre ‘STOP’ on.Then output 10ms high level signal,10ms low level signal,cycle 100 times : Select PULSE mode.Set positive pulse width to 0.010 and negative pulse width to 0.010.Delay time to 5.000.Number of pulses to 0100.

5>.Delay 5s after power ON.Then keep output : Select PULSE mode.Set positive pulse width more than 0(any value) and negative pulse width to 0.000.Delay time to 10.00.Number of pulses to ‘----’.

6.Use steps:

1>.Connect to power supply.

2>.Select work mode as following manual.

3>.Short or long pre on ‘FREQ+’ or ‘FREQ-’ to set parameter.

4>.Short or long pre on ‘DUTY+’ or ‘DUTY-’ to set parameter.

5>.Connect to load.

7.Application:

1>.Square wave signal , generating square wave signal for experimental development

2>.Used to generate a square wave signal that controls the motor driver

3>.Generate adjustable pulses for use by the MCU

4>.Dimmer

5>.Speed governor

8.Note:

1>.It’s 1-channel signal output signals.

2>.Its maximum output current is 30mA.Therefore it cannot directly drive high-power devices.

3>.Please read use manual and descrtion before use.
