Compact 5000 EtherNet/IP Adapter Power
Requirements
The adapters provide power to I/O modules as follows:
• System-side power that powers the I/O modules and lets them 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 that powers some Compact 5000™ I/O modules and
field-side devices that are connected to them.
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 adapter and passes across the I/O module internal circuitry
via power buses. The MOD power bus and SA power bus are isolated from
each other.
