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 SMART transmitter power supply KCD2-STC-Ex1 and SMART repeater KCD2-SCD-Ex1 are associated apparatus according to IEC 60079-11. The SMART transmitter power supply KCD2-STC-Ex1 provides SMART transmitters with power in field (hazardous) area and transfers the 4mA … 20 mA (or proportional 1V … 5V) analogue values in the control (safe) area up to 375Vdc. The SMART transmitter power supply KCD2-STC-Ex1 can profit of a separate input to passively sense a 4mA … 20 mA signal coming from an active source and transfer it to the safe area. Only one input at time must be used. On both configurations digital signals may be superimposed on the analogue values in the field (hazardous) or control (safe) area and may be transferred in both directions.
