Failsafe DM-F PROFIsafe digital module
Safety-related function
The safety-related function comprises:
● The safe state is the OFF state (enabling circuits opened)
● Tripping of a motor by controlling the actuators (the contactors that switch the motor on
and off) in a safety-related way.
● Safety-related evaluation of data that is received from a fail-safe controller (F-CPU) via
the PROFIsafe profile over the bus and system interface.
Standard function (non-safety-related)
The non-safety-related standard function comprises
● Operational control of the actuators (contactors) that switch the motor on and off
● Diagnostic information (e.g. safety-related tripping)
The DM-F PROFIsafe fail-safe digital module is available in the following versions:
● 24 V DC:
