The DPC system (Diagnostic Power Conditioner) is a power supply system for the installation of FOUNDATION? fieldbus H1 segments.

The module rack consist of a backplane and

the actual rack system for the power supply

modules.

The single components of the system are

electrically linked via the connection terminals

of the backplane.

Redundant power supply via a 6-pin screw

connector. The connection to the host system

is established via a removable 3-pin screw

terminal.

The H1 segment is connected separately on

the fieldbus side via 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.

A connection to the relay alarm contact is provided for redundancy monitoring of the external power supply and the H1 power supply

modules. In good-condition (no error) the relay is energized and in bad-condition the relay is de-energized.

The following error states are possible:

■ External power supply < 18 VDC

■ Power supply module, drop out or lacking

■ Power supply module, short-circuit resp.

overload

■ Module rack for two power supply modules

to connect a redundant H1 segment

■ Redundant power supply

■ Removable terminal blocks with screw

connections
