Expansion System Enhances Arduino Opta microPLC

The DIN-rail D1608x Pro Opta Digital Expansion improves the Arduino Opta's real-time control, monitoring, and predictive-maintenance abilities. It adds 16 programmable inputs for connecting digital sensors and eight more relays to operate machines. The I/Os are managed from the Opta base unit, using the open Arduino ecosystem or PLC IDE IEC 61131-3 programming environment. Programmable as digital 0 to 24 V DC or analog 0 to 10 V, you can choose between eight EMRs at 250 V AC for 6 A each, or eight SSRs at 24 V DC for 2 A, with up to five snap-on modules managed to multiply and mix I/O sets.

The DIN-rail Opta Digital Expansion extends hardware capabilities, enabling I/Os to work with PLC IDE for IEC 61131-3 PLC languages. Its low code approach and pre-mapped resources are leveraged with real-time remote monitoring via intuitive Arduino Cloud dashboards and secure communication to a wider set of connected devices.

Options include the Pro Opta Ext D1608E, with 16 digital programmable voltage inputs and eight electromechanical relays at 250 V AC and 6 A, and the Pro Opta Ext D1608S, with 16 digital programmable voltage inputs, eight solid-state relays at 24 V DC and 2 A. All units have a -20 to +50°C operating temperature range.
