4-Channel Relay HAT for Raspberry Pi

Relays are always good to have especially for electronics projects. Relay itself offers two main benefits:

• Isolation of low voltage system against high voltage system, example 5VDC and 240VAC
• Allow electronics with low voltage to control high power load, example from Arduino to AC light bulb.

This shield uses SONGLE relay, providing 4-channel input and output. The relays are isolated in the PCB. All the channels can control up to 24V DC or 250V AC on 10 A. It allows you to control high-power components like lights and motors via Raspberry Pi. Just plug it directly into your pi with 5 V. You will find a LED that indicates the status of the relays.
