Step 6 - Select:
y
one power supply for each chassis
y
a power supply bundle if you are planning a
redundant power supply system
Selecting Power Supplies
ControlLogix power supplies are used with the 1756 chassis to provide 1.2V, 3.3V,
5V, and 24V dc power directly to the chassis backplane. Non-redundant (1756-PA72,
-PB72, -PA75, -PB75) and redundant (1756-PA75R, -PB75R) power supplies are
available.
Selecting a standard power supply
You mount a standard power supply directly on the left end of the chassis, where it
plugs directly into the backplane. The power supply you select can determine which
chassis you can use.
