## Summary description

The Arduino 4 relays shield allows you to control up to 4 devices with ease. It is compatible with Arduino boards and certified with FC and CE. Measuring 53 mm in width and 68.5 mm in depth, it weighs only 44 g, making it lightweight and easy to integrate into your projects. Perfect for automation and control applications.

## Long description

The Arduino 4 Relays Shield (A000110) is a plug-in expansion board compatible with Arduino mainboards that enables control of higher-power loads which cannot be driven directly from Arduino digital pins. The shield integrates four mechanical SPDT relays (each with NO and NC contacts) and status LEDs for each channel. It is CE and FC certified, measures 53 mm × 68.5 mm, and weighs approximately 44 g, making it suitable for compact automation and control projects.
Advantages
The shield provides four independent relays on a single board, allowing simultaneous control of multiple devices. Each relay has both normally open (NO) and normally closed (NC) contacts for flexible wiring. Integrated LEDs show relay states at a glance, and the board is designed for straightforward stacking on compatible Arduino boards. Compact dimensions and light weight simplify integration into prototypes and permanent installations.
Suitable for
 Home automation — switching lights, fans and appliances
 Industrial control — driving motors, valves and actuators (within relay ratings)
 Prototyping and educational projects that require controlling mains or high-current loads
Key specifications
 Model: Arduino 4 relays shield A000110
 Relays: 4 × SPDT (NO and NC contacts)
 Certifications: CE, FC
 Dimensions: 53 mm (W) × 68.5 mm (D)
 Weight: 44 g (approx.)
 Compatibility: Designed to plug into Arduino mainboards
 Indicators: 4 status LEDs (one per relay)
How to use
Mount the shield onto a compatible Arduino mainboard by aligning the header pins and pressing gently until seated. Connect the device(s) to the relay terminals using appropriate wiring rated for the switched voltage and current. Use Arduino digital output pins to drive the relay control inputs according to the board’s pinout; consult the official Arduino documentation for example sketches and wiring diagrams. Ensure the external loads do not exceed the relay contact ratings and provide a common ground if required by your circuit.
Использование и рекомендации
The shield is intended for switching external loads within the relay ratings; always verify voltage and current requirements, follow safety rules when working with mains voltage, and add suitable protection (fuses, snubbers) as needed.
