These were pulled from a working steam turbine for power generation for an upgrade from S7-400 to S7-1200 and the software upgrade from v7.4 tov8.2.1.  They have again been tested and are in working order.

Backplane is URH-2

The three cards are the PS 405 power supply, the 414-4H PGCPU, CP 443-1 ProfiBus Interface all X2 for redundancy. 

This is a two-controller setup identical on the same backplane and synchronize via the fiber cables so there is a bumpless transfer if the master faults out for any reason.

I have two of these if you need two, we can work out a deal.  There are a couple of the plastic covers that are missing on the second one that the Engineer says, "are around here somewhere”, for what that’s worth.

Please let me know if you have any questions and I will try to get the Engineer to answer them.  I tried to list what I was told by the Engineer but sometimes I swear he speaks Vulcan.  When I ask him to say it again in English, he just switches to High Valyrian.

Thanks
