General information
3.1
Intended use
The valve coupler FD0-VC-Ex4.FF is a field device for the F
OUNDATION
fieldbus system which corresponds
to IEC 61 158/ISA-S50.02 standards. Connection of the device within hazardous areas can be established
corresponding to the FISCO or the Entity model. When connected corresponding to the Entity model, the
device meets the F
OUNDATION
fieldbus Physical Layer Profile Identification type no. 111.
The valve coupler is used to operate intrinsically safe low power auxiliary valves and their final position feed-
back contacts (sensors or mechanical switches) within hazardous areas, e.g. in the chemical and petroche-
mical industries. The valve coupler is used in ignition protection II (1) 2G EEx ia IIC T4. Supply is via a power
repeater. Data are transferred bi-directionally via the fieldbus to other devices and to a higher-level PLC or
PCS.
The protection of operators and plant is not ensured unless the device is used for the purpose
intended.
