Sample Project
Planning guide
In-/outputs:
connection technology: Spring terminals
(0.5–1.5 mm², rigid or flexible conductor);
plug-in terminals. Module replacement should
be possible with no additional tool required.
4.
Definition of in-/outputs
The modular systems can be expanded and adapted to the relevant requirements using various plug-in I/O modules.
The system can therefore be adjusted or expanded at any time.

System concept
Take into account module current
consumption for the 5V bus and the
+V bus. Payload data varies depending
on the in-/output module.
