Figure 2: Recommended AC Power Supply Configuration
In this configuration, 24V with a limited current is available on the two rightmost pins, labeled DC
PWR, of the same P3 connector. This can be used to power the analog portion of the integrated I/O
module although the available current may not be sufficient for the specific application. Refer to the
hardware manual of your corresponding I/O module for details.
4.2.2 Recommended DC Power Supply Configuration
This configuration uses a single power supply to power the controller board and 5601 I/O module.
Refer to the System Configuration Guide for more information. The power supply is used to power
the analog circuitry for the 5601 I/O module.
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.
