Feature: 1. Adopt RC voltage reduction. 2. 220V 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. Specification: Item Type: Trigger Delay Relay Module Voltage: AC 220V Maximum Relay Current: 10A Trigger Mode: Low-level signal, can be connected to buttons, proximity switches, RC receiver module After the module is powered on, the relay does not operate. When triggered (short the button or the sensor receives low-level signal), the relay immediately closes, outputs 220V voltage and starts timing. When the time is reached, the relay opens to turn off the output. Triggering again in the process of the delay is invalid. 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). Package List: 1 x Trigger Delay Relay Module
