Power Modules
There are four power modules: the IEPDS01 System Power
Module and IEPDF01 Field Power Module require 24 VDC
inputs, the IEPDS02 System Power Module and IEPDF02 Field
Power Module require 48 VDC inputs. The IEPDS01 and
IEPDS02 modules provide 5 VDC, ±15 VDC and 24 VDC out-
puts. The IEPDF01 and IEPDF02 modules provide only 24 VDC
output for field powered devices.
Module Mounting Unit
The IEMMU01 Module Mounting Unit provides the housing,
power connections and signal conductors for power supply and
process control modules. The IEMMU02 Module Mounting Unit
has the same functionality as the IEMMU01 Module Mounting
Unit, but it is a front-mounted unit. Its primary use is in
smaller system cabinets like the MINI 90™ system.
Power Mounting Unit
The power mounting unit (PMU) segregates power modules
from INFI 90 process modules. It provides housing and power
connections for IEPDS01 or IEPDS02 and IEPDF01 or
IEPDF02 power modules. The PMU is capable of supporting up
to 12 power modules (provided that its output current capacity
of 100 amps is not exceeded).
There are two PMU models. The IEPMU01 Power Mounting
Unit is a rear mount unit, the IEPMU02 Power Mounting Unit
is a front mount unit. Both PMU units mount in an INFI 90 or
Network 90

system cabinets.
FEATURES
The modular power system requires less cabinet space than
conventional systems, yet it offers features found on larger
power supply systems.
•
The DC modular power system accepts redundant 24 VDC
input or redundant 48 VDC input. The DC transfer card in
the power entry panel automatically transfers the input
source if one source fails.
•
Power modules provide scalable power for logic and I/O
functions through N+1 redundancy. With N+1 redundancy,
power modules equally share total power output. If any
module fails, the others adjust their output to meet the
total system load.
