The DPC (Diagnostic Power Conditioner) system is a power supply system for installing

FOUNDATION? fieldbus H1 segments. The

system provides extensive diagnostic options

for monitoring FOUNDATION? fieldbus segments and thus supports plant-wide 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 individual components of the system are

electrically linked via the connection terminals

of the backplane. From an electrical perspective, the backplane is to be considered to be

passive.

The power can be supplied via two 2-pole

screw connectors. The connection of the host

system is established per segment via removable 3-pole screw terminals. For the connection of the H1 segments to the fieldbus side,

each segment is individually connected with a

removable 3-pole screw terminal.

NOTE: If H1 applications are to be set up redundantly at the DPC system, they must be

connected to the field port as the host port is

limited to 21 mA.

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.
