Feature:1. INTERFERENCE RESISTANCE: The switch output adopts optocoupler isolation to enhance interference prevention ability2. WIDE APPLICATION: The relay has long service life and is widely used to control on off of solenoid valves, water pumps, motors, etc.3. FUNCTION: Multifunction trigger delay time module switch has power off memory function, which can save the setting parameters4. CYCLE PROCESS: The delay relay is turned on for a period of time after power on, and then closed for a period of time, and the above process is repeated5. SIMPLE OPERATION: This is industrial grade circuit board with stable performance and the output is DC 5‑30V, AC 220V 10ASpecification:Item Type: Trigger Delay Time Module SwitchMaterial: ABSMotherboard Size: Approx. 65 x 35mm / 2.56 x 1.38inTiming Range: 0s-999min AdjustableSupply Voltage: DC 5VOutput: DC 5-30V, AC 220V 10AQuiescent Current: 20mAWorking Current: 50mALife: >100000 TimesWorking Temperature: -40~85℃How to Use:The countdown starts after power on.Press k1 for the first 3 times to set the power on time, and the last 3 times to set the power off time. Press K1 to change the position of the time setting, and press K2 to change the number. After the digital tube does not flash, press K2 to change the decimal point position. The timing range varies according to the decimal point position:XXX. Timing Range: 0~999 MinutesXX.X Timing Range: 0 ‑ 99.9 SecondsXXX Timing Range: 0~999 SecondsAfter finishing the time setting, you can long press K2 to switch the digital tube.Package List:1 x Trigger Delay Time Module Switch
