5.1 Max. ambient temperatures

The SITRANS I100 isolators can be used over a wide temperature range. Depending on
the isolator version and installation method different maximum ambient temperatures may
result.

5.2 Power dissipation

Data sheets are describing the maximum power dissipation in standard operation (output
20 mA; power supply 24 V DC; load = 250 Ω). In practice not all isolators are working with
full load. Therefore engineering is done typically with an average power dissipation of 70 %
(P
).
