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.
