12V Relay Module Digital Timing Delay Programmable Trigger Switch with Optocoupler Isolation Item Type: Relay Module Relay Voltage: 12V Input Voltage: DC12V power supply Output Load: Within DC 30V, maximum 10A; within AC 250V, maximum 5A. Trigger Signal: High Level: 12V, Low Level: 0V Quiescent Current: 20mA Working Current: 60mA Working Temperature: -25℃-85℃ Power off Memory: Yes Working Parameter Setting Description: Press and hold the K1 button without letting go, the display will show P-xx after 2 seconds, press K2 and K3 to change the working mode. After selecting the working mode, short press the K1 key to enter the A time setting, and the screen displays Axxx. At this time, press the K2 and K3 keys to modify the A time parameter. Press the K4 key to set the position of the decimal point. After setting the A time, press the K1 key to set the B time, and the screen displays bxxx. At this time, press the K2 and K3 keys to modify the B time parameter. Press the K4 key to set the position of the decimal point. After setting the B time (when the mode has the C cycle number parameter), press the K1 key again to set the c cycle number, the screen displays Cxxx, at this time press the K2 and K3 keys to modify the c cycle number parameter, K2 and K3 keys Short press plus and minus 1, long press to fast plus and minus 10, after the setting is completed, press the K1 key one time to exit the setting state and save all parameters. The Position of the Decimal Point and the Description of the Time Unit: x.xx, the decimal point is in hundreds, the time range is 0.01-9.99 seconds xx, the decimal point is in the tens place, and the time range is 0.1-99.9 seconds xxx, no decimal point, time range 1-999 seconds xxx, the decimal point is in the ones place, the time range is 1-999 minutes Turn off the Display: In the non setting state, press K4 to turn off the display, then press again to turn it on again. Working Mode (32 Kinds): P-11: Jog mode, pull-in with signal, disconnect without signal. P-12: Self locking mode, the state of the relay flips once after each trigger. P-13: After triggering, the relay pulls in and disconnects after a delay of time A; triggering is invalid during the delay. P-14: After triggering, the relay pulls in and disconnects after a delay of A time; triggers and times again during the delay. P-15: After triggering, the relay pulls in and turns off after a delay of time A; the accumulative timing is triggered during the delay. P-16: After triggering, the relay pulls in and disconnects after a delay of A time; triggers reset during the delay (relay disconnects). P-17: After triggering, the relay is closed during the signal duration, the input signal disappears, and it is disconnected after a delay of A time; during the delay period, the relay is triggered again to remain closed, and the timing stops until the last signal disappears, and the delay A time After disconnecting. P-18: After the power is turned on, the relay will be closed immediately and will be turned off after a delay of A seconds; until the next power on. P-21: Give the signal, and the relay will be closed after a delay of time A. P-22: Give a continuous signal. After the time A exceeds, the relay is closed; the signal disappears and the relay is disconnected. P-23: When the signal disappears for more than time A, the relay is closed; when there is a signal, the relay is disconnected. P-24: Give a continuous signal. After the time A exceeds, the relay will be closed; if the signal disappears for more than the time A, the relay will be disconnected. P-25: Give continuous signal, after time A is exceeded, the relay will be closed; give continuous signal again, after time A, the relay will be disconnected P-26: Give the signal, and the relay will be disconnected after being closed for A time; after the signal disappears, the relay will be closed again for A seconds and then stop P-27: With pulse signal (rising edge or falling edge), the relay is disconnected, and there is no pulse signal. The relay will pull in after a delay of A time (continuous high level or continuous low level is considered as no pulse). P-28: After power on, the relay will be closed after the delay time A until the power is off. P-31: After power on, the relay will pull in for A time, disconnect for B time, infinite loop; power off stops. P-32: There is a continuous signal, the relay is closed for A time, disconnected for B time, infinite loop; when the signal disappears, the loop is terminated. P-33: Give a signal, the relay will pull in for A time, and disconnect for B time, infinite loop; give another signal to terminate the loop. P-34: After power on, after delaying time A, the relay will be closed, and will be disconnected after the time B is closed. P-35: Give a signal, after a delay of A time, the relay will be closed, and will be disconnected after being closed for 8 hours. P-36: Give a continuous signal. After the time A exceeds, the relay will be clos
