I am wondering how much difference there is between the X10 Pro PSC01 and the X10 Powehouse PF284.  I acquired a small handful of the PF284s and am just curous.

Given the same date of manufacture, probably none.  The best any of us here have been able to sort out, the "Pro" modules may have somewhat better quality control.

I have had vendors substitute a PSC01 for a PF284.
I also feel it is mostly the label on the case and maybe quality. At one time a X10Pro had a longer standard warranty.

dated December 2007 claims that newer versions of the PowerFlash have a substantially lower open-circuit voltage in contact-closure mode than newer versions - something like 1V versus 5V.  This would affect the ability to detect a contact closure at the end of a long wire run.

A response in the same topic indicates that standard X10 and X10pro units with 2006 date code stickers still have the 5V output.

One other thing I found with an older Date Code 02L39. In the Dry Closure Mode. The sensing voltage is opposite from the + and - Markings used to indicate the DC Input Polarity. If you are using a solid state switch it may need the leads reversed to work. My ELK-930 Doorbell Detectors solid state output didn't work until I swapped the leads.

I just noticed that myself on my PSC01 which has an output voltage of about 5.9V.  But it's missing a date code sticker so I can't tell the vintage.

The PSC01s are the newer ones being sold today.  The PF284s are the older ones if I am not mistaken.

If you have a voltmeter. Just put it in the day contact mode and measure the voltage on the + and - terminals.
My old one reads almost 6 volts with no load on it other than the meter.
