Solid State Relay Module 5V 1/2/4/8 Channel SSR Board for Arduino Raspberry Pi

About this deal

This solid state relay module is available in 1, 2, 4, or 8 channel configurations and is based on the Omron G3MB, switching AC loads up to 2A at 240V. Compared to traditional mechanical relays, SSR modules offer a longer lifespan, much faster on/off switching speeds, and silent operation with no clicking noise. It is aimed at makers and electronics enthusiasts who need to switch high-voltage AC loads safely using low-voltage digital signals from microcontrollers such as Arduino or Raspberry Pi. Optical isolation ensures electrical separation between the control and load sides, and the solid-state design eliminates mechanical contacts, resulting in reliable high-frequency switching and an extended service life. Typical applications include temperature and speed control, light adjustment, servo control, and use in medical or industrial instrumentation.
