Description: This product is suitable for robotics, car lamp delay, intelligent product development, automation equipment, PLC development, intelligent home, burglar alarm delay, and development of electronic. It features effective performane, delay time control, anti-reverse diode, and high/Low level trigger signalsification: 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. 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 terminalage Includes: 1 × Timer Relay Module
DC12V Delay Relay Board with Adjustable Signal Trigger Turn Off Delay Timer Switch Module with Anti-reverse Diode

- [Effective Performane]:The 12V trigger delay normally open relay module, and it is effective for repeatedly triggering.
- [Anti-reverse Diode]:The power supply terminal has anti-reverse diode for protection.
- [Delay Time Control]:The delay time can be adjusted by potentiometer, and it defaults 0-25 seconds. A larger capacitance or potentiometer is required if you need more time.
- [High/Low Level Signals]:The trigger signal can be high level or low level signals, and it is suitable for industrial control. The module can be triggered repeatedly.
- [Widely Used]: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.
