Module with 10A/250VAC (10A/24VDC) relay

Industrial module based on the ESP32-S3 microcontroller, which supports WiFi, Bluetooth and RS485 interface. Equipped with 6 high-power relays (up to 10A at 250VAC/30VDC), it allows for safe control of various devices and integration with industrial sensors via the Modbus protocol. The module supports popular programming environments such as Arduino and MicroPython, making it ideal for AIoT and remote monitoring applications. Waveshare ESP32-S3-Relay-6CH

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.
