Opta RS485 - Industrial-Strength PLC for Legacy & Modern Indian Automation

Modbus TCP & RTU, Dual-Core Processing, Secure Remote Control

The Reliable Choice for Indian Factories, Utilities, and Modernizations

The Arduino Opta RS485 enables smart automation for both legacy and new facilities, thanks to its STM32H747XI dual-core MCU and fieldbus integration. Built for India's unique blend of old and new infrastructure, it supports Modbus RTU/RS485 & TCP/IP and real-time, cyber-secure automation with OTA updates and robust relay outputs[10].

• Works with traditional and modern machine protocols in Indian plants.
• Remote monitoring via Arduino Cloud or custom dashboards for predictive maintenance or live control.
• Hardened security, industrial certifications, and proven reliability from Arduino & Finder partnership.
