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 power supply module provides up to

30 VDC and 800 mA for the installation of an

H1 segment. The network topology can be extended to 1900 m, due to the high output power.

If two power supply modules are connected,

the segment can be operated redundantly.

The modules can thus be plugged and unplugged during operation (hot-swappable in

run).

Due to complete galvanic isolation,

■ H1 to H1,

■ H1 to internal supply,

■ H1 to the diagnostic module ,

■ H1 to HSE diagnostic bus,

formation of parasitic voltages is avoided and

error-free communication is guaranteed.

Local comissioning and diagnostics are supported by the following LED indications:

Pwr: green: Operational readiness

ON/OFF: yellow: Output ON:

Load: yellow: Consumer (field device) detected at segment:

Com: yellow: Communication display

Fault: red: Short-circuit message
