3.3 Safety Function and Safe State
Safety Function
The device transfers analog signals from the input to the output with a deviation
of less than 2 %.
Safe State
The safe state of the application is introduced when the output drops below the valid range.
For currents the limit is 3.6 mA, for voltages the limits are 0.9 V or 1.8 V depending
on the device version.
Reaction Time
The reaction time for all safety functions is < 50 ms.
