Arduino Opta micro PLC

Arduino Opta key features and specifications:

  • MCU – STMicroelectronics STM32H747XI microcontroller with 1x Arm Cortex-M7 core up to 480 MHz, 1x Arm Cortex-M4 core up to 240 MHz, 2MB flash, 1MB SRAM (as found in all Portenta H7 boards, and I suspect there may be one inside…)
  • Storage – 16MB Flash QSPI
  • I/Os
    • 8x Digital/Analog (0-10V) input
    • 4x NO relay output contacts, rated 10 A
  • Communication Interfaces
    • Ethernet RJ45 port for LAN or MODBUS TCP/IP
    • Optional RS485 port for MODUS RTU connection
    • Optional WiFi & BLE integrated module
  • USB – 1x USB 2.0 Type-C port power, programming, or data logging (via memory stick)
  • Security – ATECC608B secure element
  • Misc – RTC, Reset and User buttons, various status LEDs for I/Os and Ethernet
  • Supply Voltage – 12…24 V DC input
  • Dimensions – About 90 x 85 x 69 mm (DIN Rail mountable)
  • Weight – 210g
  • Ingress Protection – IP20
  • Three models will be offered: the Opta Lite (8A.04-8300) will all default features, the Opta Plus (8A.04-8310) adding the RS485 ports, and the Opta Advanced (8A.04-8320) with both RS485 and a wireless module for WiFi and Bluetooth LE. The main uses case include industrial automation (Industry 4.0), building automation, and Smart Cities infrastructure,
  • The micro PLC/PLR supports both traditional PLC languages such as LADDER, FBD, or other IEC/EN 61131 languages that usually require a license, and the free Arduino 2.0.0 IDE with a range of open-source libraries. Another advantage of Finder’s partnership with Arduino is support for the Arduino IoT Cloud dashboards for real-time remote monitoring and OTA firmware updates.
