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 intrinsically safe barrier types HiC2025HC e HiC2031HC are galvanically isolated associated apparatus.
The HiC2025HC module provides the supply of two wire (4 ÷ 20mA) intrinsically safe transmitter located in hazardous area and transfer the received signal (4 ÷ 20mA or 1 ÷ 5V) to apparatus placed in the safe area; In addition, the barrier is also able to measure the input signal from active intrinsically safe transmitters.The HiC2031HC module transfers a (4 ÷ 20mA) signal from apparatus placed in safe area to devices placed in hazardous area such as smart I/P converter, electrical valves op positioners.
Both barriers may be superimposed, on the analogue signals, a digital SMART communication signal as input or output and may be transferred in both directions.
The ambient temperature may vary in a range of -20°C to + 60 °C.
