I/O system S20 and S67E – I/O systems for flexible automation

Real-time communication with the peripherals

With the increased networking of machines, the scope and importance of control peripherals are also growing. Bosch Rexroth provides users with a comprehensive and high-performance I/O portfolio for this purpose. The I/O systems S20 and S67E reduce the engineering effort by means of easy integration. With high performance thanks to very short update times and the highest synchronicity, they provide data communication in real time, allowing for higher control quality between the controller and peripherals. The fully modular design of the I/O systems provides with maximum flexibility for the economical realization of customized machine concepts.


IP20 I/O system S20 for the control cabinet


IP67E I/O system

The S67E I/O system supports the globally established IO-Link communication standard and thus enables future-proof machine topologies by connecting intelligent sensors and actuators. Due to the robust design with IP65/IP67 protection and high EMC immunity, the modules are ideally suited for field installation and enable maximum flexibility for individual solutions. Even under extreme ambient conditions, they offer reliable, machine-oriented installation without the need for a control cabinet.

  • Protection class IP65/67
  • IO-Link Master according to specification V1.1
  • Open standard according to IEC61131-9 for integration of external devices
  • Extended temperature range from -25 ... +60°C as standard
  • Gateways for PROFINET and EtherCAT
  • Preventive maintenance through operating hours counter/wear indicator/diagnosis
  • Simple installation due to reduced wiring effort
