RPi Relay Board (B)

The RPi Relay Board (B) is an expansion board with 8-ch relays for Raspberry Pi.
It gives your Pi the ability to control high voltage products such as home appliances.

Features

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards and Jetson Nano

High quality relays, loads up to 5A 250V AC or 5A 30V DC

Photo coupling isolation, prevents interference from high voltage circuits

Standard rail mount bottom case

Onboard LEDs for indicating relay status

Relay control pin selection jumper, allows control via custom pins instead of default pins

Reserved control interface, allows operation with controllers such as PLC

Comes with development resources including examples in wiringPi, bcm2835, Python, python-bottle (webpage control), and crontab (cron job)

What is the board used for and what loads can it switch?

It adds eight relays to a Raspberry Pi to switch high voltage devices. Each channel handles up to 5A at 250V AC or 5A at 30V DC, with photo coupling isolation to reduce interference.

Which platforms are compatible with this expansion board?

It supports Raspberry Pi series boards and Jetson Nano, and uses the standard 40 pin GPIO header. Trigger signals can be 3.3V or 5V.

How do I power and control the relays, and what is the jumper for?

The board uses a 5V power supply and accepts 3.3V or 5V trigger signals. A relay control pin selection jumper lets you choose custom pins instead of the default, and there is a reserved interface for PLC devices.

What comes in the package and how is it mounted?

The package includes the RPi Relay Board (B), a rail mount bottom case, and screws. It measures 232 x 72 mm and uses screw terminals for connections.
