RD72-DC-12V Infinite Cycle ON Off Relay Module DC 12V Adjustable Delay Time Trigger Delay Switch Infinite Loop Relay

【SETTING TIME】With start / stop function, the module enters infinite cycle mode after starting, and the relay works on and off according to the set time.【DELAY TIME】 Infinite-cycle power-on and power-off modules, the delay time can be adjusted separately, the longest delay can be 1000min.【SAVE ENERGY】 Low power consumption of the control board, less than 1W.Passive output (dry contact), a set of normally open + normally closed. The maximum should not exceed 10A.【WORKING VOLTAGE】The button is required to be unlocked (ie self-resetting). It can also be connected to external voltage . When the voltage is lower than 2V, it is low level. When the voltage is higher than 2V, it is high level. The maximum input should not exceed 30V.【TURN ON EXTERNAL WIRING BUTTON】 Passive switch input. The green light turns on after starting, and stays in the red light after stopping.
