Timer Module, DC12V Adjustable Cycle Times Switch Module Trigger Turn Off Delay Timer Switch Relay Module

• 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.
• Load Capacity: AC 250V 10A; DC 30V 10A. 12V trigger delay normally open relay module, multiple triggers are valid.
• Adjustable Timer Module: The delay time can be adjusted with a potentiometer (decrease clockwise, increase counterclockwise), the default is 0-25 seconds, if you need more time, just replace a larger capacitor or potentiometer.
• use: The trigger signal can be a high-level or low-level signal, suitable for industrial control, and the module can be triggered repeatedly. The power terminals are equipped with anti-reverse diodes to provide protection.
• Widely used: Timer relay 12v can be used in robotics, automotive light delay, smart product development, automation equipment, PLC development, smart home, anti-theft alarm delay and electronic product development.

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. 52 x 16mm/2.04 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 Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
