Zero-Relay

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

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.
