ctrlX I/O

I/O system for connectivity in automation

ctrlX I/O station

Connectivity is the foundation for a successful digital factory. Smooth communication between machines, systems and operators via an I/O system enables the full potential of automation to be exploited. Networking is essential for smart processes and new business models. The ctrlX I/O portfolio expands ctrlX AUTOMATION with additional interfaces to the field and control levels. The ctrlX I/O portfolio is based on EtherCAT, interface diversity and safety technology. This means that users are ideally equipped for the future and can benefit from efficiency and flexibility.

The features for more connectivity

ctrlX I/O station

Compact and modular I/O portfolio

The I/O system ctrlX I/O can be accommodated in the control cabinet in a space-saving manner. Up to 16 I/O points across a width of 12 mm support a high density of input and output signals. The ergonomic mechanical design allows modules to be replaced quickly. Removable peripheral plugs with push-in technology also enable tool-free and automated wiring. Downtimes are minimized with a clever diagnostic concept at the module and channel levels. The robust system has an IP20 protection rating and enables maintenance- and trouble-free operation in the control cabinet. Performance functions also offer flexible expandability of the I/O system.

EtherCAT as far as the terminal

As an I/O system, ctrlX I/O offers maximum connectivity and enables connection to EtherCAT, one of the largest industrial ecosystems for I/Os, slaves and fieldbus devices. This makes real-time data processing possible at the machine control level. Other established communication standards such as IO-Link are also supported. Users benefit from a virtually unlimited portfolio of powerful and freely combinable interfaces for automation.

Reduced engineering workload

The simulation of I/O and peripheral levels and the use of digital twins for offline commissioning are key to reducing the engineering workload and using third-party devices. The ctrlX Configurator provides optimum support for the selection and configuration of ctrlX I/O stations, making it quick and easy to achieve the correct design.

Ready for the future thanks to connectivity

Thanks to its impressive connectivity, the I/O system is designed for future-proof automation and is therefore open to future trends. Upgrades, remote updates and ongoing extensions are easily possible. With the co-creation concept, partners can contribute to the Ecosystem by developing their own ctrlX I/O modules, allowing them to benefit across the board.
