5V 12V Delay Relay Module Automobile Start Delay Switch with Optocoupler Signal Trigger Adjustable Time

Working principle: This module is an external signal trigger delay module. Specifically: 1)--to->2)--to->3)--to->4). 1) Supply power to the module (12v or 5V), and the relay will pull in immediately (at this time, the status of the module output terminal is: normally open and public conduction, normally closed and public disconnection) 2) The relay is disconnected after a delay of 0-25 seconds (at this time, the output status of the module is: normally open and public disconnection, normally closed and public conduction) 3) Keep disconnected until the external trigger signal triggers, the relay will pick up again 4) After the successful triggering, the relay will be disconnected after a delay of 0-25 seconds. Notes: If the trigger signal is always on, it will always be closed until the trigger signal disappears. open. (At this time, the relay returns to the state before the trigger, normally open and common disconnection, normally closed and common conduction). In addition: (the trigger signal of this module can be provided by a separate power supply system and the power supply of the module may not be the same power supply system, and the trigger level can be either a high-level pulse or a low-level pulse, which is highly versatile) Module Features: 1. Length*width=52mm*16mm 2. The working voltage of the module is 12V 3. The module can control: 10A 250VAC (AC), 10A 30VDC (DC) loads below. 4. The time can be adjusted by the potentiometer and the default is 0-25 seconds. If it takes longer, you can replace the larger capacitor or potentiometer yourself. You can also contact customer service before delivery, and we will ship it after you have changed it for you. 5. Delay time formula: T=1.1RC. For example: capacitor 47uf resistor 500K T=1.1*500000*0.000047=
