X20 system

The X20 System is the ideal addition to a standard fieldbus and expands the possibilities of standard control systems. Simply connect it, configure it, and you're done. Teamed up with other B&R components, the X20 System achieves its full potential and allows the implementation of applications with unimagined performance and flexibility. Seamless integration is a major advantage.

3 x 1 = One

Three basic elements result in one module: terminal block – electronic module – bus module.

This modularity results in a system that combines the advantages of both rack and I/O slice systems:

Prewiring without the module

Hot pluggable electronics

Extra bus slots for added options

The X20 System is distinguished by a 50% increase in component density, perfected connection technology and optimal granularity.

Added value

12 channels with a width of 12.5 mm allow a component density never before achieved with optimal terminal ergonomics. As a result, the X20 System offers 50% more channels than conventional slice systems. And this without sacrificing terminal connections.


Consistent implementation of 1-wire, 2-wire or 3-wire connections - no additional jumper terminals needed.


One channel and two channel modules: Maximum flexibility so you only have to pay for what you really need.

Available modules include:
