The ShillehTek 1-Channel 24V Relay Module lets an Arduino or Raspberry Pi control a single device like an electronically controlled on/off switch, while the relay side is powered from a 24V supply. It is ideal for industrial-style automation builds and control boxes where 24V is already standard and you need one switched output for a light, fan, pump, valve, or solenoid. This module gives you a clean, reliable way to switch loads from a simple GPIO trigger signal without building the driver circuit yourself.
