Special Features

  • Trigger Repeatedly-12V trigger delay normally open relay module, repeatedly triggering effective
  • Time Adjustable-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.
  • Protection-Power supply terminal has anti-reverse diode for protection
  • Trigger Signal-That can be high level or low level signals, suitable for industrial control, the module can be triggered repeatedly
  • Wide Application-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

Description

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: 52*16mm/2.04*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
