Safety function
Measuring temperature is the safety function with the temperature transmitters.
It is applicable for output currents from 4 to 20 mA and ensures an accuracy of ± 2% in the
maximum measurement range.
The output value will be updated at least every 620 ms (filter time constant of the electrical
damping = 0 s).
The partial system is of type B. The calculations are valid for the operating mode with low
demand rate in single-channel operation. The specific values are listed in the manufacturer
declaration for the product (Declaration of Conformity, Functional Safety according to IEC
61508 and IEC 61511): Certificates (Page 83) .
