More features

• Photoelectric isolation safety protection: The EL817 optocoupler isolation technology is used to achieve electrical isolation between the control end and the load end, effectively preventing electromagnetic interference and high-voltage shock from damaging the control circuit (such as the microcontroller), and improving system reliability
• Low voltage & high precision control: Supports 3V/3.3V low-level drive, can be directly connected to the IO port of the microcontroller (such as Arduino, Raspberry Pi, etc.), without the need for additional level conversion modules, simplifying the development process, and adapting to the Internet of Things and embedded scenarios
• High-power load control capability: The SRD-DC03V-SL-C relay can achieve load control up to 10A/250VAC or 10A/30VDC, which can drive high-current devices such as motors, lamps, and household appliances, and has a wide range of application scenarios
• Industrial-grade durable design: The relay has a lifespan of 100,000 operations, is equipped with a diode freewheeling protection circuit (to prevent back-EMF shock) and an anti-interference dual power supply design, and is matched with a 20ms fast response to meet the long-term stable operation requirements of industrial environments
• Ready-to-install engineered structure: The compact size (70×17×20mm) with rotating crimp terminals (anti-loosening) and fixed mounting holes supports quick wiring and stable installation; the built-in status indicator provides real-time feedback on the working status, reducing the difficulty of debugging
