Overview

Arduino Opta is a reliable, uncomplicated micro PLC with integrated Industrial IoT features. This device was co-developed with Finder, a top supplier in industrial and building automation, allowing users to upgrade automation projects and benefit from the Arduino environment. It caters to PLC developers, with both Arduino sketch and prevalent PLC languages - ex. LD (Ladder Logic Diagram) and FBD (Function Block Diagram) - supported.

Its powerful STM32H747XI dual-core Cortex®-M7 M4 MCU allows users to perform real-time control, monitoring and implement predictive maintenance applications.

Secure and durable by design, it supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the onboard secure element and X.509 Standard compliance.

All while maintaining Arduino Pro’s signature easy deployment in production thanks to a vast range of readily available software libraries and Arduino sketches.

Last but not least, various connectivity options make keeping everything under control effortless via real-time dashboards combined with the intuitive Arduino Cloud (or third-party services).

Opta comes in three variants so you can choose the best option for your project. Opta RS485 features Ethernet onboard and USB-C programming ports and RS485 half duplex connectivity interface.

Program it with the Arduino PLC IDE!

The Arduino PLC IDE makes PLC programming easy. Choose any of the 5 programming languages defined by the IEC 61131-3 standard (Ladder, Functional Block Diagram, Structured Text, Sequential Function Chart or Instruction List) and quickly code PLC applications or port existing ones to Arduino Opta.

Key benefits include:

Easy and fast software development, starting from ready-to-use Arduino sketches, tutorials and libraries
Support for standard IEC 61131-3 PLC languages
Fieldbus integration via Modbus TCP (ethernet) and Modbus RTU (serial RS485)
Real-time remote monitoring via intuitive Arduino Cloud dashboards (or third-party services)
Security at the hardware level thanks to onboard secure element and X.509 Standard compliance
Secure OTA firmware updates and Cloud device management
High-power relay switching (4 x 2.3 kW)
Reliable by design, thanks to industrial certifications and Finder’s expertise in switching technology
Easy to install, with DIN rail compatibility

Opt in to industrial automation

Integrate a solid and reliable micro PLC with your existing machines, devices and production lines – also in combination with other elements in the modular and versatile Arduino ecosystem, from small and smart sensor-packed modules to SOMs to gateways, for end-to-end solutions that can be customized to meet any need.

Quality by design

Arduino Pro partnered with Finder, a leader in the field of electromechanical and electronic components with 65 years of excellence and expertise to its name, to create a product with high-quality production specs for even the most demanding work conditions in industrial environments.
