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 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.
