Overview

Product Overview

The 2-Channel 24V Relay Module lets an Arduino or Raspberry Pi control two devices independently while powering the relay side from a 24V supply. Each channel acts like an electronically controlled on/off switch, so your code can toggle two separate loads for automation projects, control boxes, and test setups. This is ideal for industrial-style builds where 24V is already standard and you want clean, reliable switching without wiring two separate relay modules.

Questions & answers

Frequently asked questions

Yes. It is designed so an Arduino or Raspberry Pi can control two relay channels independently. The controller handles the logic signals, while the relay side is powered from a 24V supply.
ShillehTek supplies these modules with headers pre-soldered, so no soldering is needed before connecting control wiring and the 24V relay supply. You still need to wire the loads correctly and follow safe relay wiring practices.
It means the relay side of the module is powered from a 24V supply. It does not mean Arduino or Raspberry Pi GPIO pins should receive 24V; keep controller signal wiring separate from relay power and load wiring.
It is suited for automation projects, control boxes, and test setups where 24V is already standard. Each channel works like a separate electronically controlled on/off switch for toggling two independent devices from code.
Choose this board when one controller needs to switch two separate loads and a 24V relay supply is available. Using one dual-channel module avoids wiring two separate relay boards and keeps the control setup more organized.
