Chapter 2 GuardLogix Controller System
Power Supply
For Functional Safety applications, SELV/PELV-listed power supplies are
required for both module power (MP) and sensor/actuator (SA) power.
Consider the following when you choose a power supply:
• The MP power of the Compact GuardLogix 5380 controller must be
powered by a 24V DC SELV/PELV-listed power supply.
• All local 24V DC safety I/O must be powered by a SELV/PELV-listed
power supply.
• If the SA power connector of the Compact GuardLogix 5380
controller is used, it must be powered by a 24V DC SELV/PELV-listed
power supply.
• If local 120/240V AC I/O are used in the Compact GuardLogix 5380
chassis, their 120/240V AC I/O SA power must be connected to a
catalog number 5069-FPD module.
• If any standard I/O are used that are not powered by a SELV/PELV-
listed power supply, their I/O power must be connected to a catalog
number 5069-FPD module.
Network Communication
This section provides examples of network communication configurations.
EtherNet/IP Network
The GuardLogix 5580 controller connects directly to an EtherNet/IP network
through the onboard Ethernet port and supports 10/100/1000 MBps network
speeds. A separate Ethernet communication module is not required, but can be
used in the local chassis.
Contact your local Rockwell Automation sales office or Allen-Bradley
distributor for other communication interface modules are available for use in
the GuardLogix 5580 system.
Peer-to-peer safety communication between GuardLogix controllers is possible
via the EtherNet/IP network. GuardLogix controllers can control and
exchange safety data with Safety I/O devices on an EtherNet/IP network, via
the onboard Ethernet ports or EtherNet/IP bridges.
IMPORTANT For more information on how to power the 5069 platform when a
CompactLogix or Compact GuardLogix Controller is present, see the
CompactLogix 5380 and Compact GuardLogix 5380 User Manual, publication
5069-UM001
