## Description

The RPi Relay Board (B) is an 8-channel relay expansion board for Raspberry Pi, giving your Pi the ability to switch high-voltage loads such as home appliances, lighting, motors, and other AC/DC devices. Each relay handles up to 5A at 250V AC or 30V DC, with photo-coupled isolation to protect the Pi from high-voltage interference. Connects via the standard 40-pin GPIO header and includes a jumper block for remapping relay control to custom GPIO pins. A standard DIN rail mount case is included for clean panel installation. Development resources cover wiringPi, bcm2835, Python, web control (Python Bottle), and cron job scheduling. Key Features 8 Relay Channels – SPDT contacts (NO and NC) with screw terminal connections 5A @ 250V AC / 5A @ 30V DC – Suitable for switching mains-powered devices Photo-Coupled Isolation – Protects the Raspberry Pi from high-voltage interference Status LEDs – One per relay for at-a-glance state monitoring Pin Remapping Jumpers – Reassign relay control to custom GPIO pins DIN Rail Mount Case – Standard C45 35 mm rail compatible for panel installation Reserved Control Interface – Allows connection to PLCs and other controllers Low-Level Trigger – Relays activate when GPIO output is low Specifications Power Supply: 5V Trigger Signal: 3.3V / 5V Relay Channels: 8 Contact Form: SPDT (NO + NC) Closed Current: 6 mA per channel Connector: Screw terminal block Dimensions: 232 × 72 mm Mounting Hole Size: 3.0 mm Compatibility Raspberry Pi (all 40-pin models) Jetson Nano Ideal For Home automation and smart appliance control Industrial control panels and DIN rail installations Irrigation and greenhouse automation Lighting control and scheduling Resources Waveshare Wiki (Documentation, Schematics, Demo Code)
