The DPC system (Diagnostic Power Conditioner) is a power supply system for the installation of FOUNDATION™ fieldbus H1 segments. It provides extensive diagnostic options for monitoring FOUNDATION™ fieldbus
segments and thus supports plantwide asset
management.
A DPC system consists of one or more
DPC-49-MB-RC module racks, each with up
to eight DPC-49-IPS power supply modules
and one DPC-49-ADU or DPC-49-DU diagnostics module . Up to four H1 segments for
each module rack can be operated and monitored redundantly in the FOUNDATION™
fieldbus network. The diagnostic data of the
H1 segments can be transmitted via the HSE
interface module DPC-49-HSEFD/24VDC to
the higher level Asset Management system.
The diagnostic module DPC-49-ADU is used
as a communication and diagnostic interface
between the H1 segments and the power supply module. The diagnostics module monitors
the electrical parameters and the communication parameters of the H1 segments. Operation without diagnostic module is possible.

The diagnostic information is collected in the
device and transmitted via the HSE interface
module to the higher fieldbus level (e.g. the
host) as diagnostic and alarm data. Thereby
the modules can be plugged and unplugged
during operation (Hot swap-able in run).
The device features LEDs indicating the operating status of the H1 segments. A pre-alarm
is indicated by a yellow LED, the main alarm
by a red LED. Additionally, alarm signals can
be analysed via a relay contact.
