DC12V Adjustable Signal Trigger Turn Off Delay Timer Sw

Feature:

• 
  12V trigger delay normally open relay
  module, repeatedly triggering effective.
  
• 
  Delay time can be adjusted by potentiometer(clockwise to reduce, anticlockwise to increase),
  default 0-25 seconds, if you need more time, simply replace a larger
  capacitance or potentiometer.
  
• 
  Power supply terminal has anti-reverse
  diode for protection.
  
• 
  Trigger signal can be high level or low
  level signals, suitable for industrial control, the module can be triggered
  repeatedly.
  
• 
  It can be used in robotics, car lamp delay,
  intelligent product development, automation equipment, PLC development,
  intelligent home, burglar alarm delay, and development of electronic.
  

 

Specification:


Operating Voltage: DC 12V 


Load Capacity: AC 250V 10A; DC 30V 10A


Delay Time: T(S)=1.1*R(Ω)*C(f); e.g.
if capacitor is 47uf, resistor is 500KΩ, T=1.1*0.000047*500000=25.85sec.


Size:Approx. 67 x 16mm/2.64 x 0.62"





Working Principle:


1. Power on the module (12V or 5V) and relay
is energized immediately. N.O. terminal is connected to COM terminal.


2. Relay is dis-energized after 0 to 25
seconds. N.C. terminal is connected to COM terminal.


3. Relay keeps dis-energized until there is
an external trigger signal.


4. If there is always trigger signal, relay
will keep energized until trigger signal disappears, then dis-energized after 0
to 25 seconds. Now N.C. terminal is connected to COM terminal.






Package Includes:


1 x Timer Relay Module
