Features 1、Suitable for reciprocating stroke control, or repeated on and off of equipment and product aging test. 2、Wide voltage input, support AC input. 3、Low power consumption of the control board, less than 1W. 4、Infinite cycle power on / off module, delay time can be adjusted separately. 5、Active output, the output voltage is the same as the input voltage. Do not exceed 10A. Specification Item Type: Relay Module Power Consumption: <1.0W Life: 100,000 operations Wiring Terminal: <--Live wire into the mains L line (Live wire) input <--Neutral wire into the mains N line (Neutral wire) input -->N line is connected to load N line, most appliances do not need to strictly distinguish LN line -->The live wire is connected to the load L wire. Most appliances do not need to strictly distinguish the LN wire. -->Normally closed end of the L wire output of the live wire normally closed terminal, generally need not be connected. Instructions: Time can be set under power on and power off First determine the range and unit of the delay. The two DIP switches control the on-time and off-time at the same time. They are shared. The first bit of the DIP switch is used to set the adjustment range. The OFF position is 0-10 and the ON position is 0-1000. The second bit of the DIP switch is used to set the time unit. The OFF position is seconds and the ON position is minutes. Package List 1 x Relay Module
