4-channel SSR relay module 240V/2A triggered by high state

This module allows independent control of two Omron G5LE-14-DC12 SPDT relays, supporting currents up to 10A. Thanks to built-in BSS138K MOSFETs, it can be controlled directly from 3.3V or 5V development boards such as Arduino or Raspberry Pi. Each channel is equipped with an LED to indicate relay activation and 5mm screw terminals for convenient circuit connection. Pololu 5666

The module is designed for easy and reliable switching between two different power sources. It ensures safe use of two power sources (with voltage from 1.6 to 5.5 V) without the risk of damaging components. Adafruit 5830
