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

This is a Micro USB Digital LCD Display Time Module, model number XY-LJ02, 6-30V.
It is a delay relay module with multiple functions. LCD display: strong, user-friendly, and incredibly clear. It is widely applicable to industrial control, indoor ventilation, automatic irrigation, smart homes, and protection equipment.

Features:

1.  LCD display
2. Support high and low-level triggers
3. Emergency stop function
4. Sleep mode, Wake up with any button
5. Automatically save parameters
6. Support UART Set
7. Independent of parameters
8. Continuously adjustable from 0.01 seconds to 9999 minutes
9. Optocoupler isolation. Enhanced anti-jamming capability

Working Mode:

• P1:Relay will keep ON for time OP after getting the trigger signal and then relay OFF; The input signal is invalid if get trigger signal again during delay time OP.
• P2:Relay will keep ON for time OP after getting trigger signal and then relay OFF; Module will restart-delay if get trigger signal again during delay time OP.
• P3:Relay will keep ON for time OP after getting the trigger signal and then relay OFF; Module will reset and stop timing if get trigger signal again during delay time OP.
• P4:Relay will keep OFF for time CL after getting trigger signal and then relay keep ON for time OP and then the relay will OFF.
• P5:Relay will keep ON for time OP after getting the trigger signal and then relay keep OFF for time CL and then loops the above action. The module will reset and stop timing and relay OFF if get a trigger signal again during loops. The number of cycles (LOP) can be set.
• P6:Relay will keep ON for time OP after power on without getting trigger signal and then relay keep OFF for time CL and then loops the above action. The number of cycles (LOP) can be set.
• P7:Signal hold function. Reset delay time and relay keep ON if keep getting trigger signal. Relay OFF when the signal disappears. Reset delay time when getting trigger signal again during timing.

Timing Range:

• Continuously adjustable from 0.01 seconds to 9999 minutes.
• Enter the settings interface when short press button ‘STOP’ in the OP / CL parameter modification interface(Flashing) to select timing range.
• Pay attention to the position where the decimal point moves when the button is pressed.
• Display ‘XXXX’. No decimal point, the timing range is 1 second ~ 9999 seconds.
• Display ‘XXX.X’.The decimal point is the penultimate, timing range is 0.1 second to 999.9 seconds.
• Display ‘XX.XX’. The decimal point is the third last, timing range is 0.01 second to 99.99 seconds.
• Display ‘X.X.X.X’. The decimal point is fully lit, timing range is 1 minute to 9999 minutes.
• For example, if you want to set the OP to 3.2 seconds, move the decimal point to the penultimate position, LCD will display ‘003.2’.

Parameter Description:

• OP: Turn On-time;
• CL: Turn OFF time;
• LOP: Number of cycles. The range is 1-9999tims.’—-’ means unlimited loop.

Set Parameter:

•  Enter set parameter menu by long press button ‘SET’.
•  Work mode will flash at first set the working mode. Short press the UP/DOWN button to set the working mode.
• Short press the SET button to select the working mode and enter the system parameter settings.
• In the system parameter setting interface, short press the ‘SET’ button to switch the system parameters to be modified, short/long-press the UP/DOWN button to modify value;
• Note: Short press ‘SET ’ is invalid at mode P1,P2,P3,P7.
• Enter setting interface when short press button ‘STOP’ in the OP/CL parameter modification interface(Flashing) to select timing range (1s/0.1s/0.01s/1min).
• Save the parameter settings and exit the settings interface when long-press the ‘SET’ button after all the parameters are set.
