8 Channel 5V SSR Solid State Relay Module (Low Level Trigger)

The 8 Channel 5V SSR Solid State Relay Module is designed to control high voltage AC loads using low voltage control signals from microcontrollers. It uses solid state relays which provide silent operation, fast switching and long operational life compared to mechanical relays.

This module supports low level trigger control and can be directly interfaced with microcontrollers such as Arduino/ESP32/Raspberry Pi. It is widely used in home automation, industrial control systems, lighting control and electrical appliance switching applications.
