Electrical ratings
Conductivity measuring circuit and temperature sensing circuit in type of
protection intrinsic safety Ex ia IIC only for connection to a certified intrin-
sically safe circuit.
The effective internal inductance and capacitance are negligible.
The values above apply, each as the sum of all the individual circuits of
the associated intrinsically safe supply and evaluation unit.
Special conditions for safe use
1. The relationship between the maximum permissible ambient or media
temperature and temperature class is shown in the following table:
For U i ≤ 16 V, I i ≤ 190 mA, P i ≤ 200 mW.

2. For installation, the system drawings and wiring diagrams of the mea-
surement systems should be observed.
3. The capacitance and inductance of the connecting cable has to be con-
sidered.
