Description

1) Support frequent， high-frequency on/off of circuit.

2) No noise/spark during operation.

3) No electro-magnetic interference during operation.

4) Can be used to control motor， light bulb， LED lights and strips， small pumps， solenoid valves， etc

Description about function of the board:

1) Signal triggers output， board starts to work. When pre-set delay time is reached， work stops.

2) During the delay time: there are three modes for setting:
A: re-trigger invalid
B: once re-triggered， delay time restarts
C: once re-triggered， board resets， time count stops.

3) T1 and T2 : on/off time as repeat cycles. Both T1 and T2 are adjustable.

4) Board works when there is signal. When signal is off， time count begins and after reaching pre-set time， output stops.

Specifications:

1) Size: 64.2*39.5*13mm

2) Output capacity: DC5-30V， Max current 20A (when current is higher than 5A， please add an extra heat sink to the board).

3) Working volt: DC 5-30V

4) Signal volt:DC4-27V (can use postive pole of power supply to trigger， or a button switch， PNP sensor， PLC signal， etc)

5) Working temperature range: -40~85\'C

6) Time setting memorized after power off. Adjustable time setting with three time ranges (0-999seconds with 1 second step; 0-99.9 seconds with 0.1 second step; 1-999seconds with 1 minute step )

Time setting and Working Mode details:

Selecting work mode: put the board to power. Long Press K2 for two seconds to enter mode select. There are four modes to choose， from P1-1 to P1-4.

Mode P1-1: Signal triggers output to start work. When pre-set time is reached， work stops.
We can set the output time T: Press K2 once， first digit of LED start to shine. Press K3， number on the first digit changes; Press K2 again， second digit shines. Press K3 to change number on the second digit... And in this way we change numbers on the LED. Press K2 again， LED stop shining. Press K3 again， decimal point starts to move on the LED. When decimal point is behind third digit， time setting is 0-999 minutes. When it is behind the second digit， 0-99.9 seconds. When there is no decimal point， the time range is 0-999 seconds.

After the time setting， short press K1 and we can make minor changes: by default setting， trigger is invalid during the set delay time. When we press K1 once， the trigger becomes valid (time count restarts). Press K1 again， the board resets during set delay time(time count stops， output resets). Press K1 again， repeat this change cycle...


Work Mode P1-2: signal triggers time count. When T1 is reached， output begins. When T2 is reached， circuit disconnects. We can set the wait time T1 and work time T2: time setting is as per setting in mode P1-1. The only difference is that when LED blue is on， we are setting T2. When Blue LED is out， we are setting wait time T1.


Work Mode P1-3: Circuit on for T1 seconds， and off for T2 seconds， this goes on for infinite circles. We can set T1 and T2 as per in mode P1-1.

Work Mode P1-4: When signal triggers， output begins to work but time count does not begin. When trigger signal is off， time count begins. When the set time is reached， output is off. During the delay time， when we give signal again， the delay time is cancelled and board keeps working. When the signal is off， time count restarts. We can set the time as per in mode P1-1.
