10 I/Os Relay Module - CPU ESP32 (Relay Output)
6 units available with a short lead time.
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.
