2.3 Topology and application
2.3.1 Remote control units and I/Os on the vehicle bus
Decentralization is also becoming increasingly important in vehicle and special-purpose machine construction. The
reasons for this are obvious:
•
Reduction of production costs
•
Simplification of the wiring harness
•
Flexible expansion of machine functionality
•
Reduction of maintenance costs
•
Easy option handling
•
Lower overall system costs
The sensors/actuators and associated control electronics are therefore connected remotely directly in the engine
compartment, in the cabin or outdoors. The modular design of the B&R system makes it possible to adapt the
degree of automation to customer requirements.
2.4 Wiring without effort
Classic I/O systems are centrally located in the control cabinet. The cabling of sensors and actuators is complex.
Remote I/O modules only reach their full rationalization potential if additional distribution boxes can be completely
eliminated. I/O modules with IP69K protection for open use even in harsh environments are the solution here.
Prefabricated wiring harnesses simplify and shorten the assembly times directly at the machine or system. The
finished X90 mobile system configuration is already installed in the system and only needs to be connected to the
preinstalled wiring harnesses.
The X90 mobile system reduces the effort for manual wiring to a minimum.
2.4.1 Assemble, connect, ready
The four mounting points allow the X90 mobile system to be installed quickly and easily using the screws. The
customer can screw the device onto any flat mounting surface in any position. Vibrations in the environment also
have no influence on the functionality of the system due to the stable internal structure.
Due to the possibility of assembling the modules, the individual X90 mobile system is assembled at B&R and only
needs to be installed by the customer. This reduces cabling effort to a minimum.
Quick installation
Installation is quick and easy: The X90 mobile system
is fixed to a flat mounting surface with four M6 screws.
The mounting orientations are freely selectable and
possible in all directions.
4 option boards
An extensive range of components enables all require-
ments to be covered simply, cost-effectively and with-
out risk. Additional inputs, outputs or interfaces can be
supplemented by option boards.
CMC header
The CMC headers form the interface to the modules
and thus supply the complete system. Attaching the
connector is very simple: Push the connector into the
female connector and lock the connector in place by
pressing down the bracket.
M12 circular connector
With the X90 mobile system, the number and type of
field-assembled connectors can vary depending on
the use of modules. The connectors are D-coded (Eth-
ernet / POWERLINK). A distinction is made between
screw clamp terminal blocks and cage clamp terminal
blocks. The connectors are inserted into the coupling
and screwed tight.
