S20 (IP20)
I/O system for the control cabinet
- Compact, modular, and simple
- Space-saving I/O technology for DIN rail mounting
- Individually combinable modules
- Innovative assembly and installation concept
S20 in protection class IP20 is the flexibly scalable I/O toolkit for shortest cycle
times as well as the highest precision and ensures a real-time data flow between the
control and peripherals – whether locally on the XM control or as a decentralized
I/O station.
