BEVRLINK 4 Channel Relay with 4 manual test buttons 5V

Overview

The BEVRLink relay module is a user-friendly solution suitable for users of all levels of experience. With clear documentation and easy setup, this module is perfect for beginners. It features 4 relay channels and 4 voltage-free input channels, each equipped with a button for convenient testing. The inputs can be connected without external power, and the module can send interrupts to a manager (e.g., Raspberry Pi) on input change. The onboard LEDs indicate relay status for easy monitoring. The BEVRLink relay module offers a standard rail mount bottom case, selectable I2C address, and an optional I2C 4.7K pull-up, making it simple to set up and use. Whether you're a beginner or an experienced user, the BEVRLink relay module is an ideal choice for controlling relays and inputs in your system.
