Allen-Bradley 1771-P2

The auxiliary power supply can power one bulletin 1771 I/O chassis when used with an adapter module, a 1772 Mini-PLC-2[ processor, or a 1772 Mini-PLC-2/15[ processor. When mounted separately, the power supply can be mounted above or next to the I/O chassis. It can not be mounted below since it is necessary to allow convection cooling of both the power supply and the I/O chassis. A minimum vertical distance of six inches should be maintained.

The power supply is protected from overcurrent at its inputs by a slow-blow fuse. The power supply comes with one 1A slow-blow fuse installed for 120V operation. If you are using the power supply for 220/240V operation, remove the 1A fuse and replace it with the 0.5A slow-blow fuse that is provided.
