In module subrack BGT, up to nine burner control units can be
inserted together with the PFA 700, while with the PFA 710, the
maximum is eight burner control units.
The BGT is provided with a backplane with screw terminals for
simple, reliable wiring.
The conventional wide-spread systems used in industrial fur-
nace and kiln construction require bridging of large distances
for signal processing.
The field bus interface PFA is used in conjunction with the
pre-wired module subrack BGT for interworking of burner
control units PFU to industrial communication networks us-
ing PROFIBUS DP to control and monitor burners in industrial
furnaces and firing systems, e.g. in the iron and steel, glass
and ceramics, or plastics and chemical industries.
As a standardized fieldbus system, the PROFIBUS DP consider-
ably reduces development, installation and commissioning
costs compared to conventional wiring.
The use of a standard bus system offers massive benefits com-
pared to manufacturer-specific bespoke solutions. Time-tested
hardware components, standardized connection methods
and a series of tools of bus diagnostics and optimization are
available on the market from a whole range of manufacturers.
The widespread use of the system ensures that the planning
and service personnel are very familiar with how the system
operates and how to handle it and can therefore operate the
system efficiently.
PFA 700 with BGT SA-9U/1DP700
For interworking of up to nine burner control units PFU 760
for directly ignited burners to communication networks using
PROFIBUS DP. The PFA 700 is plugged into the module subrack
with printed-circuit board and rear terminal strip, together with
the burner control units.
PFA 710 with BGT SA-8U/1DP710
For interworking of up to eight burner control units PFU 780
for pilot and main burners to communication networks using
PROFIBUS DP. The PFA 710 is plugged into the module subrack
with printed-circuit board and rear terminal strip, together with
the burner control units.
