This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The isolation switching amplifier type K*A*-SR*-Ex*.W.* is used for the transmission of control commands from the hazardous area into the non-hazardous area as well as for the safe electrical isolation of intrinsically safe and nonintrinsically safe circuits.
Covered types of isolation switching amplifier K*A*-SR*-Ex*.W.* :
KFA4-SR2-Ex1.W*, KFA4-SR2-Ex1.W.LB*, KFA4-SR2-Ex2.W*, KFA4-SR2-Ex2.W.IR*
KFA5-SR2-Ex1.W*, KFA5-SR2-Ex1.W.LB*, KFA5-SR2-Ex2.W*, KFA5-SR2-Ex2.W.IR*
KFA6-SR2-Ex1.W*, KFA6-SR2-Ex1.W.LB*, KFA6-SR2-Ex2.W*, KFA6-SR2-Ex2.W.IR*
Remark: the „*“ represents alpha numeric signs (e.g.-Y1). These signs are used to describe different versions of a module. These differences do not affect intrinsic safety.
The maximum permissible ambient temperature is 60°C.
