- Feature: 12V 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 . can be high level or low level , 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: 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 . 4. If there is always , relay will keep energized until 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

ADJUSTABLE TIME: The chronopotentiometry regulation time, adjustable from 0 to 25 seconds by default, if you need more time, simply replace a larger capacitance or potentiometer. EASY TO USE: The timer switch relay module is easy to operate. You only need to turn on the power of the module, and the relay is immediately energized. If there is no power, connect the terminal to the COM terminal. DELAY: The relay module is normally open, and its can be high or low level , suitable for industrial control, and can be triggered repeatedly. WIDE USE: The timer module can be used in robotics, car lamp delay, intelligent product development, automation equipment, PLC development, intelligent home, burglar alarm delay, and development of electronic. CHARACTERISTIC: The operating voltage: 12 volts DC. The use of high-performance timing CPU design. One size: 52*16mm.
