•
An 11 to 24Vdc source connects to the DC PWR terminals on the 5232 Controller board. See
section
Recommended DC Power Supply Configuration
for an example of using a DC
power source.
•
An 11 to 24Vdc high current capacity source, such as batteries, connects to the AC PWR IN and
DC PWR IN terminals on the 5232 Controller Board. See section
•
A 5103 UPS Power Supply supplies 5Vdc to the controller board through the IMC cable and
supplies 24Vdc through the 24Vdc output. See section
3.2.6-Recommended 5103 Power Supply
for an example of using the 5103 UPS Power Supply.
CAUTION:
Power can be applied to either the AC/DC power input
OR
the DC power input of
the controller module.
DO NOT
apply power to both inputs. Damage to the power
supply may result.
3.2.3
Recommended AC Power Supply Configuration
This configuration uses a single Class 2 transformer to power the SCADAPack 32P. 24V are
available on the controller module connector P3. They are used to power the analog circuitry for the
analog input circuits on additional 5000 Series Analog I/O modules.

3.2.4
Recommended DC Power Supply Configuration
This configuration uses a single power supply to power the SCADAPack 32P. A 12-24VDC source
is applied to the DC PWR inputs (+) and (-).
The DC power supply input inrush current can be reduced if required. Some DC power supplies will
go into current limit when starting up into a high inrush current load. Battery operated systems have
high current capabilities that may cause nuisance fuse blowing. If either of these situations are
present in an installation, it possible to reduce the DC power supply inrush current by cutting link J3.
J3 is located on the controller next to the power input connector and fuses. This link may be cut in
DC applications only.
