The F811 fieldbus power system is designed
to provide redundant FOUNDATION™ fieldbus
power for Foxboro I/A Series control systems
using FBM228 modules. The F811 module
carrier has system connectors for direct
connection to two redundant pairs of FBM228
modules mounted on standard Foxboro
baseplates using the standard cables. Eight
fieldbus segments are supported. The system
comprises a carrier which accommodates
two F801 or F802 power modules operating
in redundant configuration. Failure alarms,
galvanic isolation, power conditioning and
segment termination are incorporated into
each F80x module. In applications requiring
simplex power, a single F80x module may
be used.
For extreme reliability, the module carrier
has no components and provides only
interconnections between the power modules
and the external connections.
Each F80x module has indicator LEDs to
show both its status and that of the eight
segments under power. In normal operation,

each green 'Segment' LED is lit, showing
that the segment is powered. If a segment
is shorted, this LED is extinguished, and the
red 'Alarm' LED is lit. In the alarm condition,
a normally closed, galvanically-isolated
relay contact goes to an open condition.
Connections to the alarm relay are made via
screw terminals on the F811 carrier. If multiple
F811 units are used, a common alarm circuit
can be achieved by 'daisy-chaining' the alarm
circuits.
The F80x module provides galvanic
isolation between the 24V DC input
power and the fieldbus segments, as
required by the IEC61158-2 fieldbus
standard and the Fieldbus Foundation™
FF-831 validation test for power conditioners.
There is also galvanic isolation between
the fieldbus segments, thereby preventing
multiple segment failures from ground faults
on more than one segment. Each segment has
its own fieldbus power conditioner and current
limitation. Termination of the fieldbus segment
is automatically maintained when single or
redundant F80x modules are fitted.
An F809F diagnostic module may optionally
be installed on the carrier, to automatically
collect and distribute diagnostic information
on each of the eight fieldbus segments.
Measured parameters may be viewed in the
Foxboro control system by either assigning
the F809F as a fieldbus device to segment 1
or 8 of the powered segments, or by means
of a separate fieldbus segment. Connections
for the separate segment are provided on the
carrier. For more information see the F809F
product specification.
Redundant 24V DC (nom.) input power is
connected to the F811 carrier using two-part
pluggable connectors.
Field wiring connections are available with
either pluggable screw terminals (F811-PS) or
pluggable spring clamp terminals (F811-PC).
