Compact 5000 I/O Serial Module Operation
Chapter 2
Power the Module
Compact 5000 I/O modules receive the following power types from first
component in the system, that is, the controller or adapter:
• System-side Power - Powers the system and lets modules transfer data and
execute logic.
System-side power is provided through the Module (MOD) Power
connector and is passed to each module as it is added to the system.
System-side power is also known as
MOD power
.
• Field-side Power - Powers field-side devices that are connected to some
Compact 5000 I/O modules.
Field-side power is provided through the Sensor/Actuator (SA) Power
connector and is passed to each module as it is added to the system.
Field-side power is also known as
SA power
.
Power begins at the left-most device in the system and passes across the Compact
5000 I/O module internal circuitry via power buses, that is, a MOD power bus.
The left-most device is either a controller or an EtherNet/IP adapter, depending
on whether the Serial module is a local or remote I/O module.
For more information on how to power local Compact 5000 I/O modules, see
the following:
• CompactLogix 5380 and Compact GuardLogix 5380 Controllers User
• CompactLogix 5480 Controller User Manual, publication
For more information on how to power remote Compact 5000 I/O
modules, see the Compact 5000 EtherNet/IP Adapters User Manual,
publication
IMPORTANT
The Compact 5000 I/O Serial Module does not use SA power.
However, verify that the module is installed in a position where
SA power uses DC voltage.
IMPORTANT
Remember the following:
• A system uses only one MOD power bus that starts at a
controller or adapter and passes across all modules that are
installed in the system.
• A system can use multiple SA power bus. The first SA power bus
typically starts at the controller or adapter, and
5069-FPD field potential distributors let you establish new SA
power buses in the same system.
