Replacing PFP 700/PFR 704

Since February 2008, power supply PFP 700
and relay module PFR 704 have had a black front
plate. PFP 700 and PFR 704 with a black front
plate incorporate all the previous functions of
PFP 700 and PFR 704 with a grey front plate.
The new power supply PFP 700 and the relay
module PFR 704 are interchangeable with units
of earlier construction stages.
