*) All inputs and outputs having a common 0 V ground form a group.

Technical specifications which are common to all modules are given in Section 8.3. The special technical specifications for all modules can be found in Section 8.4.

I/O Modules	Digital input and digital output modules are I/O modules which allow the
	processing of widely differing process signals with the S5-135U/155U
	programmable controller. They can also be used via an adapter casing in the
	S5-115U PLC.
