Arduino Compatible 4 Channel 5V Solid State Relay Module

The 4 Channel 5V Solid State Relay (SSR) Module provides safe and reliable switching of AC loads using low-voltage control signals from microcontrollers, PLCs, automation systems, and embedded controllers.

Designed for Arduino, PIC, AVR, ESP32, STM32, Raspberry Pi, and other control systems, this module features four independently controlled solid-state relays with LED status indicators for each channel.

Unlike traditional mechanical relays, solid state relays operate silently with no moving contacts, resulting in longer service life, faster switching, and improved reliability.

This version uses a 5V operating voltage and high-level trigger inputs, meaning the relay channel activates when the input signal is driven HIGH.
