## Description

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. Key Features Arduino Nano MCU – ATmega328P at 16MHz with 32KB Flash, 2KB SRAM, and 1KB EEPROM 10 I/O Interfaces – Optoisolated digital inputs (3.3–24V DC at 10Hz / 220V AC) and relay outputs (24V DC) Relay Outputs – Directly switch higher-voltage AC and DC loads 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 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 Alarm and security 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.
