OMRON 5V Low Trig SSR Solid-State Relay, 1-Channel Module

OMRON SSR Solid-State Relay, 1-Channel, 5V, Low-Trigger

A high-quality, 1-channel solid-state relay (SSR) module designed to work with popular microcontroller platforms. Ideal for ESP8266, ESP32, Arduino, and Raspberry Pi, as well as AVR, ARM, and STM32 systems. Solid-state relays are characterized by the absence of mechanical parts, which significantly increases their reliability during frequent and long-term operation. An additional advantage is the full galvanic isolation of the input from the output.

The module is an excellent choice for professional prototyping of electronic circuits. The product uses genuine, top-of-the-line OMRON relays, which guarantee reliability and stable operation.
