VEGAFLEX 86 • 4 … 20 mA/HART - two-wire
47615-EN-150102
Electromagnetic compatibility
Instruments in four-wire or Ex-d-ia version are designed for use in an
industrial environment. Nevertheless, electromagnetic interference
from electrical conductors and radiated emissions must be taken into
account, as is usual with class A instruments according to EN 61326-
1. If the instrument is used in a different environment, the electromag
-
netic compatibility to other instruments must be ensured by suitable
measures.
1.6 SIL qualification according to IEC 61508
The Safety Integrity Level (SIL) of an electronic system is used to as-
sess the reliability of integrated safety functions.
For detailed specification of the safety requirements, multiple SIL
levels are specified according to safety standard IEC 61508. You can
find detailed information in chapter "
Functional safety (SIL)
"
The instrument meets the specifications of IEC 61508: 2010 (Edi
-
tion 2). It is qualified for single-channel operation up to SIL2. The
instrument can be used homogeneously redundant up to SIL3 in
multi-channel architecture with HFT 1.
1.7 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
accepted as the standard in field instrumentation.
The device fulfills the requirements of the following NAMUR recom
-
mendations:
•
NE 21 – Electromagnetic compatibility of equipment
•
NE 43 – Signal level for malfunction information from measuring
transducers
•
NE 53 – Compatibility of field devices and display/adjustment
components
•
