The voltage for the type TORRIX Exd … is from 12 V to 50 V (U
m
= 253 V). The current is from 4 mA to 20 mA (Error
mode: 3.6 mA / 21.5 mA) respectively 10 mA when using RS-485. The supply voltage of the heater is 24 V ± 10 %
with a current of 160 mA.
When using the equipment in potentially explosive atmospheres please consult table 3 to table 6 for the maximum
temperatures depending on the equipment protection level and temperature class resp. surface temperature.
