Zero Relay

Zero Relay provides a solution for controlling high current/voltage devices and makes your home appliances intelligent. It could be a nice solution for controlling devices that could not be directly controlled by RPi's Digital I/Os. The standardized shield form factor enables a smooth connection with Raspberry Pi and compatibles. It is a 2 channel relay shield with 7A 250 Volts AC output and 10A 30Volts DC output ratings. Zero Relay is designed for triggering at high voltage levels.

Features

  • 2 High-quality Relay and loads up to 250VAC/7A, 30VDC/10A.
  • Standardized shield shape and design.
  • LEDs working status indicators for each Relay.
  • High-quality Relays.
  • 40 Pin Stacking Header for accessing GPIO of RPi.
  • Mounting holes


Specifications

  • Channel - 2 CH
  • Operating Voltage - 5V
  • AC Control Voltage - 7A / 250V
  • DC Control Voltage - 10A / 30V

Installation

Python

  • Stack Zero-Relay HAT on Raspberry Pi Zero or any Raspberry Pi 40 Pin GPIO header.
  • Open Terminal and clone/download the repository by typing below command in terminal:
 git clone https://github.com/sbcshop/Zero-Relay.git 
  • Your code will be downloaded to '/home/pi' directory. Use 'ls' command to check the list of directories and 'cd' command to enter directory.
 cd Zero-Relay 
  • B>'test2.py' is example code for Zero Relay. Run test2 file and play with Zero Relay by running below python command.
 python3 test2.py 

GPIO 4 Relay Not working Fix

  • Click on Start button >> Preferences >> Raspberry Pi Configuration, Then click on Interfaces Tab and make sure 1-Wire is disabled.
  • Click on OK button then reboot Raspberry pi.
