1500R/H
GSD file for ET 200MP
4.6 Input and output modules
The I/O modules form the interface between the controller and the process. The controller
detects the current process state via the connected sensors and actuators, and triggers the
corresponding reactions.
Function classes of input/output modules
The table below shows selected properties and technical specifications of different function
classes of input/output modules.

PROFINET
With analog modules
• Highest accuracy (< 0.1%)
• High common mode voltage (e. g.
60 V DC / 30 V AC), with single-
channel electrical isolation if re-
quired
With analog modules
• Universal modules
• Accuracy ≥ 0.3%
• Common-mode voltage approx.
10 V to 20 V
