The 4 Channel 5V Solid State Relay (SSR) Module is a control board that lets you switch four separate loads on and off using simple logic signals. With a 5V control input on each channel, it connects easily to popular boards like Arduino, ESP32, ESP8266 and Raspberry Pi, making it ideal for home automation, smart irrigation projects, grow-light timers and small DIY control systems.
Key features
- 4 independent channels for controlling up to four devices from one board.
- 5V control input, compatible with common microcontrollers and logic boards.
- Solid-state switching with no moving parts, so it runs quietly and without the clicking of mechanical relays.
- Compact module that mounts neatly inside project boxes and control panels.
Typical uses
- Automating water pumps and solenoid valves in drip or garden irrigation setups.
- Switching grow lights, fans or heaters on a schedule.
- Building smart-home and hobby automation projects.
How to choose / tips
- Confirm your controller outputs a 5V logic signal to match the trigger input.
- Check that your load type and voltage are within the module's rated range before wiring.
- Keep wiring tidy and use a proper enclosure for safety on mains-connected projects.
