It´s one of the most effective and modern decentralized I/O systems available on the market. It combines high functionality with a clever mechanic concept in an extremely compact design.


  • Compact and Space-Saving Design (0.5" Narrow)
  • Conceptual separation of electronic and installation layer
  • Space-saving, thin design
  • Innovative staircase-shaped wiring terminal
  • Simple "Two component" setup (Wiring and Electronic Module)

Clever Labeling and Diagnostic Concept

  • Clear identification and readability of channel states
  • Simple, time-saving installation and maintenance
  • Clear, definite labeling of channels
  • Reference designator label remains on the exchange of a module

Installation and Maintainability

  • "Permanent Wiring" enables the exchanging without the disconnection of the wiring
  • Intelligent slide and plug mechanism for simple handling (No Tools or Connectors Needed)
  • Electronic is protected against reverse polarity
  • Encoding of the electronic modules prevents from incorrect plugging

High Performance
