Product Use

Circuit construction

1. Prepare accessories, DC power supply, several wires, and control equipment needed

2. Circuit connection

The following diagram shows the connection of weak current to strong current. The working voltage can be supplied by Micro UsB5V or by terminals 6-30V

The following diagram shows the connection of the control equipment and module working voltage sharing the same power supply, ensuring that the power supply voltage is between 6V~30V

Working mode:

P1: After the signal is triggered, the relay conducts for OP time and then disconnects; During the OP time, the signal is triggered again and becomes invalid;

P2: After the signal is triggered, the relay conducts for OP time and then disconnects; During the OP time, the signal triggers a new timer again;

P3: After the signal is triggered, the relay conducts for OP time and then disconnects; During the OP time, the signal triggers a reset again, the relay disconnects, and the timing stops;

P4: Give the trigger signal, after the relay disconnects the CL time, the relay conducts the OP time, and the timer is complete， After completion, disconnect the relay;

P5: Give the trigger signal, after the relay conducts OP time, the relay disconnects CL time, and then cycles the above actions. Within the cycle, give the signal again, the relay disconnects, and the timer stops; The number of loops (LOP) can be set;

P6: After power on, there is no need to trigger a signal. The relay conducts OP time and disconnects CL time, and the above actions are repeated; The number of loops (LOP) can be set;

P7: If there is a trigger signal for the signal holding function, the timer will be reset and the relay will remain conductive; When the signal disappears, disconnect the relay after timing OP; During the timing period, if there is a signal again, the timing will be reset to zero;

Product Timing range

0.01 seconds (minimum)~9999 minutes (maximum) continuously adjustable

How to choose a timing range:

In the OP/CL parameter modification interface, short press the STOP button to select the timing range;

XXXX has no decimal point, with a timing range of 1 second to 9999 seconds

XXX. The decimal point of X is in ten places, with a timing range of 0.1 seconds to 999.9 seconds

XX. XX decimal point in hundreds, timing range 0.01 seconds~99.99 seconds

X. X.X.X decimal point fully lit, timing range 1 minute to 9999 minutes

For example, if you want to set the OP to 3.2 seconds, move the decimal point to ten and the LCD will display 003.2

Parameter description: OP conduction time, CL disconnection time, LOP cycle times (1-9999 times, "----" represents Infinite loops)

Product Parameter settings

a) Press and hold the SET key to enter the settings interface;

b) Firstly, set the working mode, which flashes as a reminder. Set the working mode by short pressing the UP/DOWN keys;

c) Short press the SET button to select the working mode and enter the system parameter settings;

d) In the system parameter setting interface, short press the SET key to switch the system parameters to be modified, and short/long press the UP/DOWN keys to modify them;

(Note: Short press SET is invalid in P-1~P3, P-7 modes):

e) In the OP/CL parameter modification interface, short press STOP to switch the timing unit (1s/0.1s/0.01s/1min);

f) All parameter settings are completed. Long press the SET key to save the parameter settings and exit the settings interface,

4 Remote data upload and parameter setting function

The system supports UART data upload and parameter setting function (TTL level);

UART:9600,8,1

Additional features

a) Automatic sleep function: In the running interface, long press the STOP button to turn on or off the automatic sleep function (L-P selection on will activate the sleep function, off will deactivate the sleep function);

b) Relay function selection: In the operation interface, short press the STOP button to activate or deactivate the relay function The relay is conducting normally when the conduction condition is met OFF 'The relay does not conduct even if it meets the conduction condition:' In the OFF state, the system flashes and displays' OUT ';

c) Parameter viewing: In the running interface, short press the SET button to display the current parameter settings of the system, which does not affect the normal operation of the system;

d) Display content switching: In the P5 P-6 mode, short press the DOWN key to switch the display content (running time/number of cycles);
