The valve coupler FD0-VC-Ex4.PA is designed for use in potentially explosive at-
mospheres. The respective maximum values of the field devices and of the valve
coupler must be considered in the sense of explosion protection (Demonstration of
intrinsic safety) when interconnecting the intrinsically safe field devices (Auxiliary
valves, sensors, etc.) with the intrinsically safe circuits of the valve coupler.
The PROFIBUS-PA valve coupler connection is a certified, intrinsically safe circuit, in
accordance with the FISCO model.
In order to ensure the intrinsic safety of the complete PROFIBUS-PA
segment, all the field devices and associated apparatus (Segment
couplers) connected to this PROFIBUS-PA segment must be certifica-
ted in accordance with the FISCO model.
Marking
The following identification is provided at the valve coupler FD0-VC-Ex4.PA:

Connections, terminal compartments, covers
The valve coupler FD0-VC-Ex4.PA has two separate terminal spaces that are pro-
tected by a sealed cover. The smaller cover 1 covers the connector terminals for the
PROFIBUS-PA connection. The larger cover 2 covers the terminals for valve connec-
Subject to reasonable modifications due to technical advances.
