Relay Shield4 Channel v1.3

The Relay Shield4 Channel v1.3 is a 4-channel relay board in Arduino shield format that plugs straight onto an Arduino Uno-style board. It lets your sketch switch four separate loads, such as lamps, fans, pumps, solenoid locks or motors, from digital pins, while the relay contacts keep the load circuit separate from the microcontroller. No extra wiring is needed between the Arduino and the relays.

Relay Shield4 Channel v1.3 Specifications

• Channels: 4 relays
• Format: Arduino shield that stacks on Uno-style headers
• Control: one Arduino digital pin per relay (see the board markings for the pin numbers)
• Load connection: terminals for each relay's switched contacts
• Version: v1.3

Relay Shield4 Channel v1.3 Applications

• Home automation: switching lamps, fans and small appliances
• Garden irrigation pumps and solenoid valves
• Electric door locks and access control projects
• Timers and thermostat projects with an Arduino
• Learning relay control in classes and STEM labs

What's in the Box

• 1 × 4-channel relay shield v1.3

Tip: Check which Arduino pins drive the relays and keep them free for that job in your sketch. Read the rating printed on each relay before connecting a load, and switch off the mains supply before wiring any high-voltage load to the terminals.
