#DC #12V #Signal #Trigger #Delay #Turn #Off #Delay #Timer #Switch #Relay #Module #0-25s DC 12V Signal Trigger Delay Turn Off Delay Timer Switch Relay Module 0-25s Features: 12V trigger 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 protection. Trigger signal can be high level or low level signals, 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. 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. Specifications: Operating Voltage: DC 12V Load Capacity: AC 250V 10A; DC 30V 10A Delay Time: T(S)=1.1xR(Ω)xC(f); e.g. if capacitor is 47uf, resistor is 500KΩ, T=1.1x0.000047x500000=25.85sec. Size: 6.7x1.1mm/2.64x0.43" Quantity: 1 Pc Note: Please allow 0-1mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
