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 module rack consist of a backplane and

the actual rack system for the power supply

modules and the diagnostics module.

The single components of the system are

electrically linked via the connection terminals

of the backplane. From electrical perspective,

the backplane is to be considered passive.

The power can be supplied via two 2-pole

screw connectors. The connection to the host

system is provided via two system cables.

Premoulded system cables are optionally

available at TURCK.

For the connection of the H1 segments to the

fieldbus side, each segment is individually

connected with a removable 3-pole screw terminal.

The shielding is achieved via insulated shield

bus or via the 3-pole screw terminal, which is

internally connected with the M5 threaded bolt

for equipotential bonding. A further M5 threaded bolt for equipontential bonding is simply

connected to the housing.

For simple diagnostics processing, a connection is provided to the relay alarm contact of

the diagnostics module.
