The 10 I/Os PLC Module with ESP32 is an industrial programmable logic controller that combines the connectivity of the ESP32 (Wi-Fi, Bluetooth LE, Ethernet, RS485) with standardised PLC connectors and optoisolated I/O. It provides a simple, cost-effective, and open-source approach to industrial monitoring and control.

Powered by 12–24V DC, the module features optoisolated digital inputs and outputs for reliable signal handling in noisy industrial environments. The ESP32's dual-core 240MHz processor, 4MB Flash, 4MB SRAM, and 2MB PSRAM provide ample processing power for complex automation tasks, while Wi-Fi and BLE enable wireless monitoring and control.
