Description

The 30A Relay HAT is a dual SPDT power relay I/O board for Raspberry Pi. Ideally suited to automation or industrial control, switching of household appliances, industrial machinery or automotive applications.

Featuring the well-documented MCP23008 8 channel GPIO expander, 30A Relay HAT is easy to setup and control via I2C. It can be used with any device featuring an I2C bus and works with 3.3V or 5V devices (eg, Arduino); by selecting the appropriate jumper (see device compatibility). Channels 0-1 are utilised for the relays, giving you an extra 6 GPIOs for use with your project.

30A Relay HAT is powered through the host Raspberry Pi using the GPIO port and can be used in-conjunction with other expansion boards (check-out our HAT RACK mounting board). Up to eight 30A Relay HATs can be used with a single Raspberry Pi. The relays are opto-isolated and can be powered independently by removing the jumper marked “Link”, so you can use an external supply to power the relays, reducing the load on the Raspberry Pi. Use of an external power supply is recommended if you plan to connect multiple HATs to your Raspberry Pi.

Features

  • 2 opto-isolated SPDT power relays with LED indicators
  • 30A / 15A @ 250V AC (NO / NC)
  • Supports up to 6mm² / 10 AWG cable
  • Heavy 2oz copper PCB
  • Easy to use interactive web GUI
  • Based on the MCP23008 8-port GPIO expander
  • Jumper selectable I2C address & GPIO voltage (3.3V / 5V)
  • Can be used with 3.3V or 5V I2C host devices (eg, Arduino)
  • Built-in user programmable ID EEPROM
  • Conforms to Raspberry Pi HAT Specifications

What’s Included

  • 1x 30A Relay HAT
  • 2x Jumper Links

Interactive Web GUI

Once installed on your Raspberry Pi, this interactive GUI allows quick & easy control of your 30A Relay HAT without the need for any coding. It is designed to be both a user guide & quick reference to the 30A Relay HAT pinout. The GUI is fully responsive and adapts to any screen size.

Check-out the Live Demo.
