Quality and electromagnetic compatibility

By using a well-shielded metal case for each module

and also installing EMC filters in each incoming and

outgoing lead, measures have been adopted to

comply with EMC standards without the need of

installation in cubicles. As a result, the Freelance

800F hardware meets the binding EMC standards

and bears the CE Mark. The requirements of IEC 801

and the NAMUR industrial standard have also been

fulfilled. A sophisticated test strategy, the installation

of optical inspection systems, and integrated self-test

functions ensure that the modules are highly reliable.

HART devices can be connected using HART

compliant modules of the S800/S900.

If the HART devices are connected to the S900.

certain S900 modules can be used to transfer

additional HART values to the cyclical I/O mapping.

This makes it possible to use the second or third

measured values of a HART device in the AC 800F

as an input for applications.
