Safety Function and Safe State

Safety Function
The device transfers analog signals from the input to the output with a tolerance of 2 % related
to the full signal range.
The attached PLC must recognize a fault when the resistance drops below 15  or rises
above 400  (for Pt100) or above 4 k (for Pt1000).
The switch position of the DIP switch on the device has no influence on the safety function.
Safe State
The safe state of the output is the high impedance state (> 100 k) or the fault state (< 15 ).
Reaction Time
The reaction time for all safety functions is < 20 ms.
Note!
See corresponding datasheets for further information.
