Feature:1. The newly upgraded relay is modular and simple to meet the daily needs of customers2. Increase the power supply anti reverse function, setting parameters can be remembered permanent after power failure3. Input and output adopt optocoupler isolation to enhance anti interference ability4. Working voltage is between 10~16V, ensuring stability, industrial grade circuit board, PLC like5. The signal terminal of the 12V relay module can maintain the voltage signal for a long timeHow to Use:Specification:Item Type: Timer RelaySize: Approx. 64.2 x 34.8 x 18.5mm / 2.5 x 1.3 x 0.7inRelay Capacity: AC 220V10A or DC30V10AQuiescent Current: 20mA Working Current: 50mAWorking Voltage: 10~ 16VSignal Voltage: 4V~20VService Life: ≥100,000 TimesWorking 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 modeP1-1-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
