Taidacent 12V NE555 Delay Relay Timer Module Delay Start Switch NE555 Relay with Switch On Delay Adjustable Timer Relay 12V
Product Description
The 12V time delay relay module is when the module is powered, the relay is released (COM and NC are connected, COM and NO are disconnected), and then the delay starts. When the time set by the potentiometer is exceeded, the relay immediately picks up. (At this time, COM and NC are disconnected, COM and NO are turned on), and the pull-in state is maintained. When the module is powered off and re-powered, it can again release the well delay pull-in. Therefore, by selecting the corresponding COM, NC, NO, the delay off or delay on function can be realized.


Delay time is adjustable (default O-10s), counterclockwise adjustment potentiometer increases delay time
Increase the capacitance C1 to increase the maximum delay time T
With input power indicator
With relay pull-in indicator
Onboard 12V, 10A/250VAC, 10A/30VDC relay (maximum control equipment 2200W)
With relay freewheel protection
Delay time formula: T=1, 1RC. For example: Capacitance 100uf resistance 100K T=1, 1*100000*0.0001=11 seconds, that is, the maximum delay time is 11S
Board size: 17*61mm
Interface Description
12V working voltage
relay normally closed port
relay common
the relay normally open point


The module can implement the delay open or delay turn-on function. The following uses a set of LED lights as the controlled device as an example:
VCC and GND are connected to DC12V working voltage, the COM pin of the relay is used as the switch input terminal, and the NC is used as the output terminal. When power-on, COM and NC are turned on by default (D1 is off, the controlled LED is lit), and the delay is started. After a certain time, COM and NC are disconnected (D1 is on and the controlled LED is off). At this point, if the module is powered back on, the module can be brought into the delay state again.
