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-DU is used

for monitoring of the external power supply

at the module rack and the function of the

FOUNDATION™ fieldbus H1 power supply

modules. The diagnostic for each segment

can be switched off separately.

The device features 3 LEDs indicating the operating status. An alarm is indicated by a red

LED. Additionally, alarm signals are analysed

via a relay contact.
