Variants
Some components of the system are available in different versions (variants). The vari-
ants are usually functionally similarly to each other/the master item, but differ in features
such as the number of power jumper contacts.
Example: 750-624/040-00x

Housing Colors
The components of the WAGO I/O System 750 XTR can be identified by their dark gray
housing, which clearly sets them apart visually from the components of the WAGO I/O
System 750/753. To allow fast identification of the intrinsically safe components of the
series, the XTR Ex i modules have a two-color (dark gray/blue) design.
Color Coding for Identifying Functionality
To allow you to quickly and easily get an overview of the component classes present in a
node, they are color-coded.
• I/O modules in the 8-channel housing can be color-coded by attaching marking ele-
ments (
ü
• I/O modules in the 16-channel housing have a color background for the installed indi-
cators.
The colors provide information about whether analog or digital signals are processed,
whether the component is an input (analog: green, digital: yellow) or output (analog: blue,
digital: red) and whether it is a power supply, function or technology module (gray).
