Introduction

The DPI620G-IS can communicate with devices that use
the FOUNDATION Fieldbus H1 implementation. This is
achieved via an integrated H1 modem.
Note: The H1 modem hardware is only included in
DPI620G-IS-FF or DPI620G-IS-FFPB.
This section provides detail of how to connect a
FOUNDATION Fieldbus device to the DPI620G-IS.

FOUNDATION Fieldbus Configurations

Before setting-up the electrical connections between the
FOUNDATION Fieldbus device and the DPI620G-IS, the
correct configuration should be established.
A FOUNDATION Fieldbus network at its simplest consists of
a field device, 2 terminators and a power supply. The
terminators and power supply are available within the
DPI620G-IS.
This allows the connection of the DPI620G-IS to:
 Already existing networks where the power supply
and termination are already present.
 Stand-alone FOUNDATION fieldbus devices.
 Any network configuration in between.
Note: The DPI620G-IS internal power supply is current
limited to approximately 30mA.
