5.2 Electromagnetic Compatibility Verification in Accordance with EC
Council Legislation Directive 2004/108/EC
Compatibility in Accordance with EN 61326-1 and NAMUR NE 21
Recommendation
The electromagnetic compatibility (EMC) requirements, applicable for electrical equipment for
measurement, control, and laboratory use in general are anchored in the international standard
EN 61326. 3 different performance criteria are distinguished in this standard:
A class A device operates as intended during the test. This device can withstand the immunity
tests without any noticeable performance degradations within the specification limits of the
manufacturer.
A class B device operates as intended after the test. The device shows temporary degradation
or loss of function of performance during the test but self-recovers from that state when the
exposures are ceased.
A class C device has loss of function. The device may need manual restoration. During the test
a temporary loss of function is allowed, as long as an operator can restore the device back to
operation.
Designation Description
HCD2-FBPS-1.500 General purpose isolated power supply module with
28 ... 30 V DC and 500 mA output.
HCD2-FBPS-1.23.500 Ex ic isolated power supply module with 21 ... 23 V DC and
500 mA output.
HD2-DM-B Basic diagnostic module with LED indication and common
relay fault output.
HD2-DM-A In combination with the FDT/DTM-based diagnostic
manager, the advanced diagnostic module (ADM) allows for
the analysis of signal and segment parameters as well as for
the measurement of specific physical layer values
concerning the system and node.
HD2-DM-A.RO The advanced diagnostic module (ADM) relay output
permanently monitors the physical layer. If a predefined
threshold is exceeded, a built-in contact opens to alarm the
operator via a system alarm input.
MBHC-FB-8R General purpose redundant segment motherboard for 8
segments with redundant bulk power feed and diagnostic
interface with plug-in screw terminal connections.
MBHC-FB-8R.1 General purpose redundant segment motherboard for 8
segments with redundant bulk power feed and diagnostic
interface with plug-in spring terminal connections.
Accessories
ACC-MB-HDC Diagnostic link cable
Coupling the diagnostic bus between 2 motherboards,
length 6 cm.
ACC-MB-CC Connector cover
Set of 2 covers with special connectors to keep clearance
distance between power and host terminals.
ACC-MB-HSK Grounding rail and 4 cable clamps used to simplify shield
connection at the trunk.
