The valve coupler FD0-VC-Ex4.FF is designed for use in potentially explosive atmos-
pheres. 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, sen-
sors, etc.) with the intrinsically safe circuits of the valve coupler.
The valve coupler fieldbus connection is a certified, intrinsically safe circuit, in accord-
ance with the FISCO and the Entity model.
When interconnected according to the FISCO model, all the field
devices and associated apparatus (fieldbus repeaters) connected to
this segment must be certificated in accordance with the FISCO model
in order to ensure the intrinsic safety of the complete FF-H1 segment.
Marking
The following identification is provided at the valve coupler FD0-VC-Ex4.FF:

Connections, terminal compartments, covers
The valve coupler FD0-VC-Ex4.FF has two separate terminal spaces that are pro-
tected by a sealed cover. The smaller cover 1 covers the connector terminals for the
FF-H1 connection. The larger cover 2 covers the terminals for valve connection and
Subject to reasonable modifications due to technical advances.
