ERbic CAN bus
The CAN bus, originally developed for automobile engine
management, is distinguished by its particularly high reliability.
Among other things, this necessitates a more complicated
protocol, which leads to lower data rates and cable lengths.
This can be compensated for in part by larger cable cross
sections. Data rates reach 1 Mbit/s. The 9-pin Sub-D
connector is standardized as the interface to the device.
In some cases, a version with a shield coupling capacitor is
available as an option (cable shield <-> housing Sub-D).

to be identified with the CE marking according to EU direc-
tives.
* Due to continuous advancement, it is possible that the UL approval of a new version may not have been completed at the time of
going to press.
