Note 3: Intrinsically safe, entity, for Class I, Division 1, Groups A, B, C and D;
Class I, Zone 0, AEx ia IIC, Ga (entity) for hazardous (classified) locations when
installed per control drawing D&E 2020-023-A50.
Sensor input parameters:
Ui= 18 V; Ii= 170 mA; Pi= 0.4 W;
Li= 0.1 mH (models with fixed cable) or Li= 0 mH (VS/VP type);
Ci= 150 nF (models with fixed cable) or
Ci= 0.4 nF (VS type) or Ci= 0 nF (VP type).
Ambient temperature:
-40 °C to +40 °C for temperature class T6,
-40 °C to +55 °C for temperature class T4 and T5,
-40 °C to +105 °C for temperature class T3.
When the sensor has been connected to non intrinsically safe equipment which
exceeds the restrictions regarding the sensor input circuits, the sensor is not
suitable anymore for intrinsically safe use.
* Certification is subject to change, due to new regulations or changes in the product itself.
When a certificate is updated, a new revision under the same certificate number is created
with a new date.
