["for DC 12V DDC-431 Timer Delay Relay Switch Digital Data Save Delay Controller for DC 6V-30V\n\nDescription:\n- Powerful function, one-button emergency stop function (STOP button), with reverse connection for protection, reverse connection without burning, power-off memory.\n- Increased sleep mode, after enabling, No operation within 5 minutes, automatically turn off the display, wake up any button! \n- You can set different OP, CL, LOP parameters, these parameters are independent of each other, save the setting parameters automatically power-down save and other functions, almost meet all needs!\n \nProduct manual:\nWorking voltage: DC6V-DC30V (wide voltage anti-connection for protection)\nTrigger signal source: high-level trigger for DC 3.0V—24V signal ground and system ground to improve the system's anti-interference ability can also short-circuit the ground\nOutput capacity: controllable for DC 30V/10A or AC 250V/10A equipment\nProduct size: 64mm*35mm*19.3mm\nMounting hole: diameter 3mm\nWorking temperature: -40 ° C ~ 85 ° C\n\nOperating mode:\nP1 mode: After the signal is triggered, the relay turns on the OP for time, then turns off; in the OP for time, the following operation\nP1.1: The signal is triggered again.\nP1.2: Signal triggers re-timed again\nP1.3: The signal triggers reset again, the relay is disconnected, and the timing is stopped.\nP-2: Give the trigger signal, after the relay turns off the CL for time, the relay turns on the OP for time. After the timing is completed, the relay is turned off.\nP3.1: Give the trigger signal, after the relay turns on the OP for time, the relay turns off the CL for time, then loops the above action, the signal is given again in the cycle, the relay is disconnected, the timing is stopped; the number of cycles (LOP) can be set\nP3.2: No trigger signal is required after power-on, the relay turns on OP for time, the relay turns off CL for time, and the above actions are cycled; the number of cycles (LOP) can be set\nP-4: Signal hold function If there is a trigger signal, the timing is cleared, the relay remains on; when the signal disappears, the relay is turned off after timing the OP; during the timing, there is a signal, and the timing is cleared.\n \nRelay enable mode:\nON : The relay is allowed to conduct during the OP conduction for time.\nOFF : The relay is prohibited from being turned on and is for always off.\nShort press the STOP button on the main interface to switch between ON and OFF. The current state will flash, then return to the main interface. This function is the emergency stop function, one button to open and close the relay.\n\nSleep mode (long press the stop button to view the current mode)：\nC-P sleep mode: within five minutes, without any operation, the digital tube automatically turns off the display, the program runs normally.\nO-d normal mode: the digital tube is for always on display\nPress and hold the STOP button for 2 seconds and then release to switch the C-P and O-d states. The current state will flash and then return to the main interface.\n \nTiming range:\nHow to choose the timing range\nAfter setting the parameter value in the mode selection interface, press the STOP button to select the timing range.\nXXX. Decimal point is in one place, timing range: 1 second to 999 seconds\nXX.X decimal point in ten, timing range: 0.1 seconds to 99.9 seconds\nX.X.X. The decimal point is fully illuminated, the timing range is from 1 minute to 999 minutes.\nFor example, if you want to set the OP to 3.2 seconds, move the decimal point to ten digits, and the digital tube displays 03.2.\nParameter description: OP on for time, CL off for time, LOP cycle number 1-999 times, \"---\" stands for infinite loop\nThese parameters are independent of each other, but each mode shares these parameters. For example, when the on-time OP is set to 5 seconds in P1.1, the user wants to switch to the P1.2 mode, then when entering the P1.2 setting corresponding parameters, the OP also Will be 5 seconds\nDisplaying 000 on the main interface and pressing the SET button will display OPL, LOP and corresponding for time XXX\nIf only OP in the mode, such as mode P1.1, P1.2, P1.3 for time, then short press SET button will only display OP and corresponding for time\nIf the mode has OP, CL, LOP such as mode P3.1, P3.2 short press SET button will display OP and corresponding for time, CL and corresponding for time, LOP and corresponding times\nAfter setting the mode, it is very convenient to view the parameters set in the current mode by pressing the SET button on the main interface.\n\nHow to set parameters:\n1) First determine the working mode of the relay\nAccording to the working mode of the relay, in the main interface (when the module is powered on, it will flash the current working mode (default P1.1 mode), then enter the main interface \"press and hold the SET button for 2 seconds and then release\" to enter the mode selection. Interface, select the mode to be set
