Relay 12V Timer Delay NE555 Module

DESCRIPTION:

• DIMENSIO: 6.8CM * 2.1CM 
  
• IC: NE555
  
• OPERATING VOLTAGE: 12V
  

QUICK SPECS:

• Delay time adjustable (0- 10s)
  
• You can add the delay time by adding potentiometer;
  
• You can increase the delay time by increasing the capacitor C1; 
  
• With the input power indicator;
  
• With relay actuation indicator;
  
• This relay can control device below AC 220V/10A (Max 2000W)
  
• With relay freewheeling protection;
  
• Delay time formula: T = 1.1RC. For example: Capacitor 100uf resistance 100K T = 10.1 * 100000 * 0.0001 = 11s
  
• When the power is on, the relay is time-delay closing:
  
• When you offer 12v to the relay, it will not pull in immediately and the output status >>Normal open is not connected with common, while Normal close connected with Common; after 1-10s(adjustable) delay, Normal open is connected with Common while Normal close disconnect with Common.

PROJECT IDEAS:

• Apply with mobile unit, delay the connection to prevent excessive current damaging the device;
  
• Prevent burning appliances when multiple devices are simultaneously starting and causing over-current.
