## Description

The 10 I/Os Relay Module with ESP32 is an industrial PLC that combines the connectivity of the ESP32 (Wi-Fi, Bluetooth LE, Ethernet, RS485) with relay outputs for switching higher-voltage loads. It provides a simple, cost-effective, and open-source approach to industrial monitoring and control with standardised PLC connectors. Powered by 12–24V DC, the module features optoisolated digital inputs and relay outputs for switching AC and DC loads. The ESP32's dual-core 240MHz processor, 4MB Flash, 4MB SRAM, and 2MB PSRAM provide ample processing power, while Wi-Fi and BLE enable wireless monitoring and IoT integration. Key Features ESP32 MCU – Dual-core 240MHz with 4MB Flash, 4MB SRAM, and 2MB PSRAM 10 I/O Interfaces – Optoisolated digital inputs (0–3.3–24V DC at 10Hz) and relay outputs (5–24V DC) Relay Outputs – Directly switch higher-voltage AC and DC loads Wi-Fi & Bluetooth LE – Built-in wireless connectivity for IoT and remote monitoring Standardised PLC Connectors – Industrial-grade connectors for reliable wiring RS485 Communication – Modbus RTU support for industrial networking Ethernet Port – TCP/IP and Modbus TCP connectivity USB Programming – Program via Arduino IDE or ESP-IDF over USB 12–24V DC Power – Operating range 11.4–25.4V DC, rated power 30W, max current 1.5A Specifications Operating Temperature – 0°C to 60°C Operating Humidity – 10%–90% Storage Temperature – -20°C to 60°C Ideal For Industrial machine monitoring and control AC and DC motor control HVAC systems (fans, pumps, air conditioning) Elevator control systems IoT-connected industrial automation Production line automation Warning: This module can switch mains-voltage loads via relay outputs. Mains voltage wiring must be performed by a qualified electrician. Incorrect wiring can result in electric shock, fire, or equipment damage.
