8 Channel PoE Relay Module - a module with 8 relays and Ethernet communication

Compact module with MOSFET IRF520 24V/5A transistor.

This XIAO ESP32-C6-based relay module is designed for intelligent automation. It allows independent control of six channels via Wi-Fi, Zigbee, Thread, or BLE, and thanks to the built-in ESPHome, it easily integrates with Home Assistant. It supports DC devices up to 30V, features two Grove ports for expansion, and comes in an aesthetically pleasing PLA enclosure. Ideal for IoT systems, home automation, lighting, and motor control.

This SPST solid-state relay module allows for safe switching of DC circuits up to 60 V and 7 A, offering galvanic isolation and low conduction resistance (approx. 30 mΩ) thanks to the use of back-to-back MOSFET transistors. It features fast switching time (up to 1 ms), low control current consumption (approx. 10 mA), and the ability to control a signal from 2.7 to 40 V. Its compact design, lack of mechanical components, and the ability to mount on 2.54 mm connectors or screw terminals make the module a durable and quiet solution for systems requiring reliable isolation and long service life.
