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.
