SPECIFICATIONS

Product parameters:
main chip: NE555
working voltage: DC 12V/5V

1. power on relay delay closing. Specifically:
after supplying 12V/5V power to the relay, the relay will not suck immediately. the state of the output end of the
electrical appliance is: normally open and publicly disconnected, normally closed and publicly
connected. after a delay of 1~10s (adjustable), the relay sucks and
. at this time, the state of the output end of the relay is: normally open and publicly connected,
normally closed and publicly disconnected; As long as the module is continuously powered, this status will-be guaranteed.
2. delay time adjustable,(1~10 seconds)
3. adding potentiometer can increase delay time
4. increasing capacitor C1 can increase delay time
5. with input power indicator
6. with relay pull-in indicator
7. can control AC 220V/10A-down equipment. (Maximum control equipment 2000W)
8. With relay freewheeling protection.

Applicable occasions:
1. Delay the on-board equipment to prevent excessive current from burning the on-board equipment when the car is on fire.
2. the need for sequential start-up occasions, to prevent multiple devices at the same time start the current is too large to burn electrical appliances.

Features:
1. length * width = 52mm * 16mm,
2. module working voltage 12V
3. module controllable:
10A 250VAC (AC),10A 30VDC (DC) below load.
4. time can be adjusted by potentiometer default 0. 25 seconds, need longer time,
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 of wiring.
7. The signal end of the module is designed with optocoupler isolation, strong anti-interference ability,
can adapt to the application of low-level two control signals, suitable for industrial control.

8. the module can be triggered repeatedly (such as setting a delay of 10S, in a certain trigger 1 0S delay again trigger action, otherwise in the again

re-delay 10S when working, that is, the next trigger
within the end of the non-delay shall prevail, and delay 10S backward until the delay time reaches to complete the whole process of one trigger delay. After this delay is over, the
is triggered again, and the delay is
9 again. No power consumption in standby (almost no power consumption in standby, zero current, extending the life of the car battery.
product application: available thousands of robots, car lights delay, intelligent product development, automation equipment,
PLC development, smart home, anti-theft alarm delay, electronic development and so on

Working principle:
This module is an external signal trigger delay module. Specifically: 1) -to->2)-to->3)-to->4).

1. Supply 12V power to the module, and the relay is immediately closed (at this time, the state of the output end of the module is normally open and publicly on, normally closed and publicly off).
2. After a delay of 0-25 seconds, the relay is disconnected (at this time, the output state of the module is normally open and publicly off, normally closed and publicly on).
3. Keep disconnected until triggered by an external trigger signal, the relay is closed
again.

4. After successful triggering, the relay will be disconnected after a delay of 0-25 seconds. Note: If the trigger signal is present, the relay will be closed until the trigger signal disappears. The module starts to delay timing and is disconnected after a delay of 0-25 seconds.
(at this time, the relay returns to the state before triggering, normally open and common disconnection, normally closed and common conduction).

Another: (The trigger signal of this module can be provided by a separate power supply system and the power supply of the module can be not a power supply system, and the trigger level
can be a low level pulse with strong versatility)
