XY-LJ02 6-30V Micro USB Digital with LCD Display Time Delay Relay Module Control Timer Switch Trigger Cycle Module Support UART

0.01 seconds (min) ~ 9999 minutes (max) continuously adjustable

This product with LCD display is very clear, easy to use and powerful, please read the operating instructions of this product carefully.

Module highlights.

1. with LCD display, the current mode and parameters are clear at a glance, very clear, simple and practical.

2. support high and low level triggering, switching control, suitable for most occasions.

3. wide voltage power supply (6~30V) support micro USB 5.0V power supply, very convenient to use.

4. supports UART data upload and parameter setting.

5. with one key emergency stop function (STOP key), with reverse connection protection, reverse connection does not burn.

6. add sleep mode, after enabling, no operation within 5 minutes, automatically turn off the LCD backlight; press any key to wake up.

7. different OP, CL and LOP parameters can be set, which are independent of each other and are saved separately

8. all set parameters are automatically saved by power-down. 

Operating modes.

P1: After the signal is triggered, the relay conducts OP time and then disconnects; during the OP time, the signal is not valid for re-triggering

P2: After the signal is triggered, the relay is switched on for the OP time and then disconnected; within the OP time, the signal is triggered again and retimed   

P3: After the signal is triggered, the relay is switched on for the OP time and then disconnected; within the OP time, the signal is triggered again to reset, the relay is disconnected and the timing is stopped

P4: given a trigger signal, the relay is disconnected for CL time, then the relay is switched on for OP time, and after the timing is completed, the relay is disconnected

P5: after giving the trigger signal, the relay is switched on for OP time, the relay is switched off for CL time, then the above action is cycled, the signal is given again within the cycle, the relay is switched off and the timing is stopped; the number of cycles (LOP) can be set.

P6: no trigger signal is required after power-up, the relay is switched on for OP time, the relay is switched off for CL time, then the above action is cycled; the number of cycles (LOP) can be set.

P7: Signal hold function If there is a trigger signal, the timing is cleared and the relay is kept on; when the signal disappears, the relay is disconnected after the timing OP; during the timing period, there is a signal again, the timing is cleared.

Product parameters.

1: Operating voltage: 6 - 30V support micro USB 5.0V power supply

2: Trigger signal source: high level trigger (3.0V~24V), low level trigger (0.0V~0.2V), switch control (passive switch).

3: Output capacity: can control devices within 30v 5A DC or 220v5A AC

4: quiescent current: 15mA operating current: 50mA

5: Service life: more than 100,000 times; working temperature: -40-85℃; size: 8.0*3.8*1.9cm

6: With optocoupler isolation, enhanced anti-interference capability, industrial grade circuit board, set parameters are remembered forever after power failure.

Timing range

0.01 seconds (min) ~ 9999 minutes (max) continuously adjustable

How to select the timing range.

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

XXXX No decimal point, timing range 1 sec~9999 sec

XXX.X Decimal point in the tens place, timing range 0.1 sec~999.9 sec

XX.XX Decimal point in hundreds, timing range 0.01 sec ~ 99.99 sec

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

For example, if you want to set OP is 3.2 seconds, then move the decimal point to the tenth position, LCD display 003.2

Parameter description: OP on time, CL off time, LOP cycle times (1-9999 times, "----" means infinite cycle)

Parameter setting

a) Enter the setting interface by pressing and holding the SET key.

b) First set the working mode, the working mode flashes to remind, set the working mode by short pressing the UP/DOWN key.

c) Short press the SET key to select the working mode and to enter the system parameter setting.

d) In the system parameter setting interface, short press SET to switch the system parameter to be modified, short/long press UP/DOWN to modify it.

(Note: Short press SET is not valid in P-1~p-3 and 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) When all parameter settings are completed, press and hold SET to save the parameter settings and exit the setting interface.

 Additional functions

a) Automatic sleep function: In the operating interface, the automatic sleep function is activated or deactivated by pressing and holding the STOP key (L-P selects on to activate the sleep function, off to deactivate it).

b) Relay function selection: In the operation interface, by short pressing the STOP key, the relay function is activated or deactivated. 'ON' satisfies the on condition that the relay is normally on, 'OFF' satisfies the on condition that the relay is also not on; In the 'OFF' state, the system flashes 'OUT';

c) Parameter view: In the operation interface, short press the SET key to display the current parameter settings of the system, and does not affect the normal operation of the system.

d) Display content switching: In P-5 P-6 mode, switch the display content (running time/cycle times) by pressing the DOWN key briefly;
