Today we are covering the Allen Bradley 1746-P2 Series C PLC.
This is a power supply, which we all know is the heart PLCs. Needless to say, all PLCs require a power supply in order to operate. This is why we are kicking off our PLC blog series with this incredible 1746-P2 Series C!

This particular one is a 500 Rack Mount Power Supply. The terminals on this power supply provide an isolated, non-fused 200 mA 24 VDC power. This item must be mounted directly on the left end of the 1746 Input / Output (I/O) Chassis.

The 1746-P2 has a selectable operation mode of 120V or 240V, which can be chosen by setting a jumper. This does not require any special wiring.
This Series, as well as other 1746-P2 power supplies, have LED that indicates proper supply power.
