Finder OPTA - Programmable Logic Relays (PLR)

The Finder OPTA is an innovative range of Programmable Logic Relays (PLRs) designed to simplify industrial, OEM, and building automation projects. Developed in collaboration with Arduino, OPTA combines Finder’s renowned reliability with Arduino’s flexible, open-source platform. This makes it easy to program using both traditional languages like Ladder and FBD, as well as Arduino’s IDE.

Finder OPTA is powered by the STM32H747XI dual-core Cortex®-M7+M4 MCU, enabling real-time operations and predictive maintenance1. It supports various connectivity options, including Ethernet, Wi-Fi, and Bluetooth, and offers secure, over-the-air firmware updates. With 8 digital/analog inputs and 4 relay outputs, OPTA is versatile and ready for a wide range of applications.

Upto five Finder OPTA expansion modules can be fitted alongside the OPTA PLR. These modules increase the number of inputs and outputs available for applications.

Function and features:

• The Finder OPTA is a Programmable Logic Relay (PLR) with 8 digital/analog inputs (0…10 V). Each input can be assigned as a digital or analog. So you can mix and match the input combination depending on the projects requirements.
  
  
• Programmable both with a traditional language (Ladder) as well as with an innovative and open source language (Arduino PLC IDE).
  
  
• Programming can be performed via integrated development environment (IDE) as an option IEC-61131-3
  • LD - Ladder Diagram
  • SFC - Sequential Function Chart
  • FBD - Function Block Diagram
  • ST - Structured Text
  • IL - Instruction List IL
    
    
• USB (Type C) high speed port for programming and power delivery, data logging (via memory stick).
