Allen Bradley power supply series substitute

[JoeTauser]

We've still got a ton a PLC 5's installed and running. We lost a 1771-P7 Series B power supply. There are a lot of 1771-P7 series D power supplies available on the surplus market.

Is there a significant difference between the B and the D? I'm guessing the D will work, but if someone could chime in I'd appreciate it.

Thanks

From what I can gather, it's the same voltage input and amperage rating. I also found this on ebay:

Should be fine. Here are the two manuals:

I have never had any issues going from a older version (B) to a newer version (D) for any of the AB products, I have had issues going to other way
