Connection block The upper part of the housing selected for the CPX I/O mod
ules is called the connection block. Connection blocks provide
the necessary connections for sensors and actuators. In this
way, the CPX terminal offers a high degree of flexibility with
regard to adaptation to different applications and operating
conditions.
