Equipment and systems covered by this certificate are as follows

The Surge Arrestor, Model D9324S protect measuring devices against surge voltages. The surge protection device is provided with a ½” NPT or M20x1,5 thread, suitable for connection to an external enclosure.

The surge protection devices conform to the requirements for a FISCO Field Device.

According to the type of protection Ex d or Ex tb and the application, the surge protection device is intended to be installed according to IEC 60079-14 on a certified enclosure. The surge protection device is only Ex d or Ex tb when installed on a certified enclosure of the same type of protection.

Electrical data

Rated voltage: max. 36 Vdc

Input circuits (3 ... 5 wires):
in type of protection intrinsic safety Ex ia IIC and Ex ia IIIC, only for connection to a certified intrinsically safe circuit, with the following maximum values:
Ui = 36 Vdc; Ii = 500 mA; Pi = 3 W; Li = 1 μH; Ci = 1.65 nF
or for connection to a circuit in accordance with FISCO.

Thermal data

The relation between temperature class, maximum surface temperature, ambient temperature and operation temperature, is listed in the table below:
 Temperature class Max. surface temperature Ambient temperature Operation temperature
