Opta Expansion
Arduino Opta® enables a wide range of real-time control, monitoring and predictive maintenance applications. It allows professionals to scale up automation projects while taking advantage of the open and widely known Arduino ecosystem.
Quickly put it to work, leveraging the many available software libraries. The onboard secure element ensures Over-The-Air firmware updates and remote control via the Arduino Cloud or third-party services.
Digital Expansion
Elevate your real-time control, monitoring, and predictive maintenance setups by integrating the Arduino Pro Opta Digital Expansions.
These expansions can significantly boost your system's capabilities by incorporating 16 programmable inputs for digital sensor connections and an additional 8 relays for efficient machine operation.

Benefits
- Inputs flexibility: 16 new inputs for your applications per each expansion added, programmable as digital 0-24 VDC or analog 0-10 V
- Powerful Outputs: choose between 8 EMR offering 250 VAC for 6A each or 8 SSR offering 24 VDC for 2A
- Up to 5 snap on modules managed to multiply and mix your set of I/Os with Seamless detection: snap it right next to your Opta Base module and use the I/Os as native Opta resources
- Extend your hardware capabilities keeping your programming comfort by using the Arduino IDE with its wide range of ready to use sketches, tutorials and libraries
- Put your new I/Os easily to work with PLC IDE for IEC 61131-3 PLC languages, taking advantage of its low code approach and pre- mapped resources
- Extend the Opta’s benefits of Real-time remote monitoring via intuitive Arduino Cloud dashboards and secure communication to a wider set of connected devices
- Reliable by design, thanks to industrial certifications and Finder’s expertise in switching technology
- Easy DIN rail installation
Applications
- Automated Production Line
- Real-time Monitoring in Manufacturing
- Automated Anomaly Detection
Analog Expansion – Coming Soon!
Bring your security measures to new heights, prioritizing both safety and effectiveness. Implement rigorous physical security measures, including door access and motion detection meticulously overseen by analog sensors. Real-time data from sensors guide access control, alarm systems, and surveillance, while Arduino Opta regulates locks and entry points with impeccable precision.

Benefits
- Inputs flexibility: 6 analog inputs programmable by the user to work in the 0-10 V or 0/4 to 20 mA or even to measure temperatures in the range -25 °C to +400 °C via 3 wires RTD PT100 sensors (2 out of 6)
- 2 configurable analog outputs to deliver 0 to 10 V or 0/4 to 20 mA
