DC 12V Signal Trigger Delay Turn Off Delay Timer Switch Relay Module 0-25s

RelaysFeatures: 12V trigger delay normally open relay module, repeatedly triggering effective. Delay for time can be adjusted by potentiometer(clockwise to reduce, anticlockwise to increase), default 0-25 seconds, if you need more for 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 for 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: for DC 12V Load Capacity: AC 250V 10A; for DC 30V 10A Delay Time: for T(S)=1.1xR()xC(f); e.g. if capacitor is 47uf, resistor is 500K, T=1.1x0.000047x500000=25.85sec. Size: 6.7x1.1mm/2.64x0.43" Quantity: 1 Pc Package Contents: 1 x Timer Relay Module
