XY-LJ02 Time Adjusted Relay Module

 

It is a timed relay module with 7 different functions. It can be powered from the 5V Micro USB input or terminals. It can be used in many smart projects. Time can be set between 0.1 seconds and 9999 minutes.

 

The setting interface is opened by pressing and holding the set button on the module. Select the mode from here and then press set again to move on to the time section. The unit of time can be changed by pressing the stop button on this screen. After the necessary parameters are entered, they are saved by pressing and holding the set key. The connection diagram is as follows.

 

 

P1: After the trigger is given Then, the relay opens for the specified time, and when the time expires, the relay closes. Even if it is triggered again, the relay does not close until the time expires and the time does not change.

P2: After the trigger is given, the relay opens for the specified time, and when the time expires, the relay closes. If it is triggered again, the time starts again. For example, if you set 10 seconds and triggered it at the 5th second, the time becomes 10 seconds again.

P3: After the trigger is given, the relay opens for the specified time, and when the time expires, the relay closes. If it is triggered again, the time returns to the beginning and the relay is reset and operation stops.

P4: The on time of the relay is entered as OP. After it is set, the off time is entered into the CL value. After being triggered, the relay, which remains closed for the CL value, opens and remains open for the OP value. Even if it is triggered again, it continues to be triggered until the time expires.

P5: The on time of the relay is entered as OP, and then the off time of the relay is entered as CL. The resulting LP value is the number of times this cycle will be repeated. For example, if OP 2 sec, CL 3s and LP 2 are entered, the relay that remains open for 2 seconds will remain closed for 3 seconds. Then it will turn on again for 2 seconds and stay closed for 3 seconds and the operation will stop. If triggered during operation, operation stops and returns to the beginning.

P6: Same as P5. The only difference is that the process does not stop even if the trigger is made.

P7: In this mode, even if a time is entered, as long as the trigger signal comes continuously, the relay opens but the time does not decrease. As soon as the signal is cut off, the relay remains open and the time starts. When finished, the relay closes.
