Working principle: This module is an external signal triggered delay module.
Specifically: 1) -- to -> 2) -- to -> 3) -- to -> 4).
● 1) Supply power to the module (12V or 5V), and the relay will immediately close (at this time, the status of the module output terminal is: normally open and common connected, normally closed and common disconnected)
● 2) After a delay of 0-25 seconds, the relay is disconnected (at this time, the module output status is: normally open and common disconnected, normally closed and common connected)
● 3) The relay remains disconnected until an external trigger signal is triggered and the relay closes again
● 4) After successful triggering, the relay will be disconnected after another delay of 0-25 seconds. Note: If the trigger signal is always present, it will be continuously energized until the trigger signal disappears. The module will start the delay timing and disconnect after a delay of 0-25 seconds. (At this time, the relay returns to the state before the trigger, with the normally open and common disconnected and the normally closed and common connected).
In addition: (The trigger signal of this module can be provided by a separate power supply system and the power supply of the module can be different from that of the power supply system. At the same time, the trigger level can be a high level pulse or a low level pulse, which has strong versatility)
Module features:
1. Length*width=52mm*16mm
2. The module working voltage is 12V
3. The module can control loads below: 10A 250VAC (AC), 10A 30VDC (DC).
4. The time can be adjusted by the potentiometer. The default is 0-25 seconds. If you need a longer time, you can replace a larger capacitor or potentiometer by yourself.
5. Delay time formula: T = 1.1RC. For example: capacitor 47uf resistor 500K T = 1.1 * 500000 * 0.000047 = 25.85 seconds.
6. The module power supply has a diode to prevent reverse connection of the power supply , so friends can rest assured to connect the wires.
7. The signal end of the module is designed with optocoupler isolation , which has strong anti-interference ability and can adapt to the application of high and low level control signals, suitable for industrial control.
8. This module can be triggered repeatedly (for example, if the delay is set to 10S, and the trigger action occurs again within the 10S delay of a certain trigger, then the delay will be set to 10S again when the action occurs again, that is, based on the last trigger before the delay ends, and then delay for another 10S until the delay time is reached to complete the entire process of one trigger delay. After this delay ends, it will be triggered again and delayed again.
9. No power consumption in standby mode (almost no power consumption in standby mode, zero current, greatly extending the life of the car battery. Green product)
Product application: can be used for robots, car light delay, intelligent product development, automation equipment, PLC development, smart home , anti-theft alarm delay , electronic development, etc.
