10 I/Os Relay Module - CPU Arduino NANO (Relay Output)

The 10 I/Os Relay Module is an industrial PLC based on the Arduino Nano 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 and support for RS485, Ethernet (TCP/IP, Modbus TCP, Modbus RTU), and optoisolated inputs.

Powered by 12–24V DC, the module features optoisolated digital inputs and relay outputs for switching AC and DC loads. The relay outputs make it suitable for directly controlling motors, pumps, solenoids, and other actuators. Program it using the Arduino IDE over USB.
