2.1 EtherCAT Box Modules
The EtherCAT system has been extended with EtherCAT Box modules with protection class IP 67.
Through the integrated EtherCAT interface the modules can be connected directly to an EtherCAT
network without an additional Coupler Box. The high-performance of EtherCAT is thus maintained into
each module.
The extremely low dimensions of only 126 x 30 x 26.5 mm (H x W x D) are identical to those of the
Fieldbus Box extension modules. They are thus particularly suitable for use where space is at a premium.
The small mass of the EtherCAT modules facilitates applications with mobile I/O interface (e.g. on a robot
arm). The EtherCAT connection is established via screened M8 connectors.
The robust design of the EtherCAT Box modules enables them to be used directly at the machine.
Control cabinets and terminal boxes are now no longer required. The modules are fully sealed and
therefore ideally prepared for wet, dirty or dusty conditions.
Pre-assembled cables significantly simplify EtherCAT and signal wiring. Very few wiring errors are made,
so that commissioning is optimized. In addition to pre-assembled EtherCAT, power and sensor cables,
field-configurable connectors and cables are available for maximum flexibility. Depending on the
application, the sensors and actuators are connected through M8 or M12 connectors.
