X20 system User's Manual 3.10
2.1.2 3 x 1 = 1
Three basic elements make up 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 delivers 50% more component density, perfected connection technology and optimal gran-
ularity.
•
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.
•
Uniformity
Consistent implementation of 1-, 2- or 3-wire connections – no additional jumper terminals needed.
•
Granularity
1-channel and 2-channel modules: Maximum flexibility so you only have to pay for what you really need.
