PROFIBUS® Communication
Note
The PROFIBUS PA® protocol is an unsecured protocol, as such
the intended application should be assessed to ensure that
these protocols are suitable before implementation.
The interface complies with Profile 3.01
(Standard PROFIBUS®, EN 50170, DIN 1924 [PRO91]).

Voltage / current consumption

• Mean current consumption: 12 mA.
In the event of an error, the FDE function (= Fault
Disconnection Electronic) integrated in the device makes
sure that the current consumption cannot exceed a
maximum of 20 mA.
