Motherboard

MBHC-FB-8R*
The motherboard MBHC-FB-8R* enables the redundant supply of 8 segments and the
connection of the FOUNDATION Fieldbus H1 host system. 16 sockets hold the power supply
modules, with 2 each supplying 1 of the 8 segments redundantly. 2 extra sockets hold
diagnostic modules.
MBHC-FB-8R: Motherboard equipped with screw terminals.
■
MBHC-FB-8R.1: Motherboard equipped with spring terminals.
■
Note!
If the motherboard is intended to be used with dedicated power supply modules and Segment
Protectors to generate Ex ic rated outputs, a connector cover has to be mounted on each
power supply terminal. 2 connector covers and special connectors come with each
motherboard.

Power Supply Modules HCD2-FBPS-*

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:
