1、Adopt RC voltage reduction. 2、 direct input and direct output, it works when connected to power supply load. 3、Can be connected to buttons, sensors, RC receiver and other modules. 4、External trigger to start the timing, short the self-reset button to start the timing. You can also short the trigger to achieve. 5、Re-triggering in the process of the delay produces no effect, and if the trigger signal still exists at the end of the timing, it will not trigger again. Only after the disappearance of the old signal, new signal can produce the action. 6、Can change the time range by yourself. The greater the capacitance of the C5 capacitor on the board, the longer the delay time. Item Type: Trigger Delay Relay Module Maximum Relay Current: 10A Trigger Mode: Low-level signal, can be connected to buttons, proximity switches, RC receiver module Function: Turn on and output immediately after triggering, and automatically judge the output after a delay of X seconds. Load Capacity: 10A (Motor products are recommended to be used below 7A due to the large starting current) 1 x Trigger Delay Relay Module
