Overall Configuration
The maximum total length of a fieldbus node without fieldbus coupler/controller is
780 mm including end module. The width of the end module is 12 mm. When
assembled, the I/O modules have a maximum length of 768 mm.
Examples:
•
64 I/O modules with a 12 mm width can be connected to a fieldbus
coupler/controller.
•
32 I/O modules with a 24 mm width can be connected to a fieldbus
coupler/controller.
Exception:
The number of connected I/O modules also depends on the type of fieldbus
coupler/controller is used. For example, the maximum number of stackable I/O
modules on one PROFIBUS DP/V1 fieldbus coupler/controller is 63 with no
passive I/O modules and end module.
Observe maximum total length of a fieldbus node!
The maximum total length of a fieldbus node without fieldbus coupler/controller
may not exceed 780 mm.
Also note the limitations of individual fieldbus couplers/controllers.

Mounting onto Carrier Rail
6.3.1
Carrier Rail Properties
All system components can be snapped directly onto a carrier rail in accordance
with the European standard EN 60175 (DIN 35).
Do not use any third-party carrier rails without approval by WAGO!
WAGO supplies standardized carrier rails that are optimal for use with the
WAGO I/O System 750 XTR. If other carrier rails are used, then a technical
inspection and approval of the rail by WAGO GmbH & Co. KG should take place.
Carrier rails have different mechanical and electrical properties. For the optimal
system setup on a carrier rail, certain guidelines must be observed:
•
The material must be non-corrosive.
•
Most components have a contact to the carrier rail to ground electro-
magnetic disturbances. In order to avoid corrosion, this tin-plated carrier rail
