Specification:Working voltage: DC 12V (normal working voltage DC10V-16V)Signal Source: DC 4V~20V (usual power supply positive trigger, button, PNP sensor, PLC signal, etc.)Output capability: It can control devices within 30v5A or within 220v5AStandby current: 20mA, working current: 50mAService life: more than 100,000 timesWorking temperature: -40~85 °CDescription:Voltage input anti-reverse circuit, worry-free wiring. Signal input optocoupler isolation, strong anti-interference ability. Set the parameter to power off permanent memory. Powerful flash MCU online programming function, according to user needs can contact the manufacturer to customize the required functions.Function:P-1: The signal triggers the relay to pull in. When the time is up, the relay is disconnected during the delay.A: Invalid trigger again B: Re-trigger re-clocking C: Trigger relay reset again to stop timingP-2: The signal trigger start timing time T1, the time is up to the relay pull-in time T2 is disconnected (reset)A: Invalid trigger again B: Re-trigger re-clocking C: Start delay without triggering power-onP-3: Cycling: Turn on T1, disconnect T2, infinite loop. For T1 and T2, the time is adjustable; if a parameter is turned ON or OFF, it can be turned on or the power is turned on.A: The relay is turned on immediately after power-on. B: The relay is turned off and then turned on after power-on.P-4: There is signal, the relay is closed, the suction is kept, the signal disappears, the timing starts, the time is up, the relay is disconnected, during the delay, the signal is given again, the delay is cancelled, the relay is kept, the signal disappears, and the time is re-timed.Usage:"Set": function selection button: long press "Set" button for 2 seconds, P-* appears, short press "Set" to select mode, press "UP" to enter mode "UP": Shift key: Press to adjust the flashing position of the digital tube, which digital tube flashes, and "DOWN" to adjust the value of the flashing digital tube. Until the "UP" is pressed, the digital tube no longer flashes, the setup time is completed, the setup time is automatically saved and the power is turned off."DOWN": When the digital tube is flashing: "DOWN" adjusts the digital change, and 0 to 9 changes sequentially.When the digital tube display is normal: "DOWN" adjusts the decimal point position. The decimal point indicates 0 to 999 minutes in ones digits; 0 to 99.9 seconds in ten digits; 0 to 999 seconds in no decimal point.Note 1: After the working mode is selected, short press "Set" to enter the function A, B, C switching, the digital tube will not display A or B or C, you need to short press "Set", trigger the signal The test only knows that the default is A.Note 2: Functions P-2 and P-3 have two sets of time to be adjusted. Press "UP" six times for one cycle, adjust the first three times for one time, and adjust the other three times.Note:The relay output is a passive contact that has no live output and controls the on/off of a line.Package Included:1 * 12V Delay Timer Relay with Case for Car
