For use in hazardous areas in circuits certified as intrinsic-
ally safe with the following maximum values:
Input circuit:
Ui = 30 V, Ii = 130 mA, Pi = 0.9 W
Li = 5 µH, Ci = 1.3 nF (5.3 nF to earth)
Ambient temperature range:
Temperature class T4: . . . . . .–40 °C to + 80 °C
Explosion protection Zone 2
It is recommended to use the positioner with explosion pro-
tection “intrinsically safe” (consider temperature class).
In the Federal Republic of Germany these positioners may
be operated in Zone 2 with non-intrinsically safe circuits if
the operating values do not exceed the maximum reference
values.
