Timer Relay Plastic 1 Way Permenent Memory Switch Adjustable Electronic Component DC 12V Item Type: Timer Relay Size: Approx. 64.2 x 34.8 x 18.5mm / 2.5 x 1.3 x 0.7in Relay Capacity: AC 220V10A or DC30V10A Quiescent Current: 20mA Working Current: 50mA Service Life: ≥100,000 Times Working Temperature: -40-85℃ Instruction:The relay is closed, the normally open end and the common end are connected, and the normally closed end and the common end are disconnected; working mode selection: After connecting the power, long press K1 for 2 seconds to enter the selection function mode P1-1-P1-4 Can Be Selected, P1-1 Working Mode: The signal triggers the relay to close, and the time is up, the relay is off. The user can set the time T for the relay to close, press K2 hundreds of digital tubes to start flashing, Press K3 at this time, hundreds digit will change; press K2 once and the tens digit will start blinking, press K3 at this time, the tens digit will change; press K2 the single digit will start blinking, and press K3 at this time, the ones digit The number changes; press K2 again; the digital tube no longer flashes, press K3 at this time, the decimal point shifts, the decimal point in the ones place means 0 to 999 minutes, the tens place means 0 to 99.9 seconds, no decimal point means 0 to 999 seconds; After the selection is made, the time is now set. Short press K1 to enter the fine adjustment setting of the function. By default, the trigger is invalid during the delay period. Press K1 to activate the trigger during the delay period (re-timing). Press K1 to reset during the delay period (timing off, relay reset). Press again to repeat the default setting for the first time. P1-2 Working Mode: The signal triggers and starts timing X time when the relay is closed and Y is disconnected. The user can set the time x and Y for the relay to close; the time setting is similar to P1-1 except that the blue light is on to set the time for the relay to close, and the blue light off means to set the time for the relay to turn off. Short press K1 to enter the fine adjustment setting of the function. The trigger is invalid during the default delay period. Press K1 to activate the trigger during the delay period (re-time). Press again to repeat the default setting for the first time. P1-3 Working Mode: Turn on for x seconds, turn off for Y seconds, infinite loop. The user can set the time x and Y for the relay to pull in; the time setting is similar to P1-2, short press K1, you can enter the fine adjustment setting of the function, first turn on x, turn off Y seconds, press K1, turn off first x, turn on for Y seconds, and press again to repeat the default setting for the first time. P1-4 Working Mode: The signal triggers the relay to close but does not start timing. The trigger signal disappears and starts timing T. When the time is up, the relay is disconnected; during the delay period, the signal is given again, the delay is canceled, the pull-in is maintained, and the signal disappears. Restart timing; (equivalent to start timing when the button is released, often used for power-off delay). The user can set the time T for the relay to close; the time setting is similar to P1-1.
