Opta Digital Expansion

The Arduino Opta® Digital Expansion is a plug-and-play extension to the Opta® PLC Controller that expands its capabilities with more inputs and outputs. Two variants are available: the AFX00005 - Opta Ext D1608E (with Electromechanical Relays) and the AFX00006 - Opta Ext D1608S (with Solid State Relays), both of them fully compatible with the Arduino Ecosystem.

Arduino Opta® Digital Expansions are designed to multiply your Opta® micro PLC capabilities with the addition of 16 programmable inputs for connecting your digital sensors and 8 more relays to operate your machines.

Designed in partnership with leading relay manufacturer Finder®, it allows professionals to scale up industrial and building automation projects while taking advantage of the Arduino ecosystem.

Arduino Opta® Digital Expansion is available in two variants:

  • AFX00005 - Arduino Opta® Ext D1608E: Electromechanical Relay outputs
  • AFX00006 - Arduino Opta® Ext D1608S: Solid State Relay outputs

Up to 5 snap-on modules managed to multiply and mix your set of I/Os with seamless detection.
