8-Channel 5V Low-Trigger SSR Relay Module for Arduino, ESP8266, ESP32, and Raspberry Pi

8-Channel 5V Low-Trigger SSR Relay Module for Arduino, ESP8266, ESP32, and Raspberry Pi

A professional 8-channel module equipped with reliable solid-state relays (SSR). The device is powered by 5 V and allows for current control up to 2 A. The module is fully compatible with popular platforms such as AVR, ARM, Arduino, and STM32. The absence of mechanical parts ensures that these relays offer a significantly longer service life and greater reliability, even under very heavy use. An additional advantage is the galvanic isolation between the input and output, which ensures a high level of system safety. It is an excellent choice for rapid prototyping and advanced electronic projects.
