Power Supply Modules HCD2-FBPS-*
Danger!
Explosion hazard from invalidation of type of protection
When using Power Hubs with suitable Segment Protectors in order to generate an intrinsically
safe field wiring, exceeding the limits of the output values can overload connected field
devices. In consequence, the field devices or the circuits themselves can produce sparks that
can ignite the surrounding potentially explosive atmosphere.
Ensure that the power supply modules used are within the limits of the required output values.
Power supply modules provide full galvanic isolation between the bulk power supply and the
segments. They provide optimum system reliability for applications where cabling and wiring
are routed through critical or harsh electrical environments. Power supply modules are the best
choice in situations, where full protection from electromagnetic interference (EMI) is
mandatory.
Power modules are connected to the motherboard via sockets. They can be exchanged while
the system is in operation. In redundant configuration, load is shared between 2 power
modules.
For different application requirements, special power supply modules are available:

Diagnostic Modules
Caution!
Property damage from plugging the wrong type of module
Plugging the wrong type of module into the connection slot labeled "Diagnostic Module only"
can damage the connection slot or the module.
Only plug HD2-DM diagnostic modules in the connection slot labeled "Diagnostic Module
only".
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 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.
For further information refer to the instructions "Basic Diagnostic Module HD2-DM-B".
Advanced Diagnostic Module
The advanced diagnostic module is a comprehensive measurement tool for the fieldbus
physical layer. It is well suited for commissioning, online monitoring and maintenance. 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 Diagnostic Manager – Basic Edition shows all
data on easy-to-use displays.
