Failsafe digital input

To enable a safety function via the terminal strip of the converter, you need a failsafe digital
input.
Which devices are you allowed to connect?
The failsafe digital input is designed for the following devices:
• Connection of safety sensors, e.g. emergency stop command devices or light curtains.
• Connection of pre-processing devices, e.g. failsafe control systems and safety relays.
Signal state
The converter expects signals with the same state at its failsafe digital input:
• High signal: The safety function is deselected.
• Low signal: The safety function is selected.

DI 0: r0722.0, ..., DI 5: r0722.5
For specific default settings of the terminal strip, e.g. default
setting 2, the converter combines two digital inputs to form
one failsafe digital input FDI 0.
