Waveshare Industrial 8-Channel ESP32-S3 WiFi Relay Module, Onboard Isolated CAN Interface with Common network port
The Industrial 8-Channel ESP32-S3 WiFi Relay Module is a robust, industrial-grade control board based on the powerful ESP32-S3 dual-core processor. WiFi Relay Module is designed for AIoT applications, it supports dual-mode 2.4GHz Wi-Fi and Bluetooth LE for flexible wireless communication. The module features 8 high-quality relays rated up to 10A (250V AC / 30V DC) and 8 digital inputs with bi-directional optocoupler isolation for reliable signal protection.
WiFi Relay Module is also includes an isolated CAN interface, USB Type-C port for power and programming, and an PoE Ethernet port compliant with IEEE 802.3af for streamlined power and data via a single cable. Built-in protection circuits, onboard RTC, TF card slot, buzzer, and RGB LEDs enable stable, secure, and intelligent control in demanding industrial environments. The module is housed in a rail-mount ABS case for easy installation and durability.
Note: This product comes in two versions- one features a POE network port, while the other has a standard network port. You will receive one of these two versions.
