Product Specifications
Fieldbus Power Supply Modules
The fieldbus power supplies supply the PROFIBUS PA segments with power. For different
application requirements, dedicated power supply modules are available:
■
HCD2-FBPS-1.500. Output: 28 V... 30 V at 500 mA with an intrinsically safe limited
voltage for Zone 2 of U
o
= 30 V
■
HCD2-FBPS-1.23.500. Output: 21 V ...23 V at 500 mA with an intrinsically safe limited
voltage for Zone 2 of U
o
= 24 V
■
HD2-FBPS-IBD-1.24.360. Output: 24 V at 360 mA for intrinsically safe (DART) segments
installed in Zone 1
The power supply modules provide full galvanic isolation between the bulk power supply and
the PA segments. The modules offer system reliability for applications where cabling and wiring
are routed through critical or harsh electrical environments, with full protection from
electromagnetic interference (EMI).
Power supply modules are plugged into the motherboard slots and can be exchanged during
system operation. In redundant configuration, load is shared between 2 power supply modules.
Diagnostic Modules
Basic Diagnostic Module
The basic diagnostic module provides basic system diagnostics. It monitors the input voltage
of the bulk power supply and each segment for overload and short circuit conditions. Each
power supply module is checked for proper function. Power supply modules operating in
redundant configuration are checked for compatibility. LEDs indicate both status and fault
information. This information can be transmitted via volt-free contact.

Advanced Diagnostic Module
The advanced diagnostic module is a comprehensive measurement tool for the PROFIBUS PA
physical layer, and supports commissioning, online monitoring, and maintenance tasks. The
module provides the exact segment and individual device data needed for detection of
changes in the fieldbus physical layer. Segment measurements include fieldbus voltage and
load current. Device-specific measurements are signal level, noise, and jitter. All data is
transmitted to the control room via Ethernet. The basic edition of the diagnostic manager
displays all data in an easy-to-use user interface. The professional edition of the diagnostic
manager offers extended software functions: the commissioning wizard generates automated
reports; the software displays clear-text messages for troubleshooting of out-of-specification
behavior.
