Hardware Modules; what board is inside your K or S series?

@Telmi

The serial number on the outside ( K50S0nnn) differs from that reported by the server in the web control ( K50B0nnns ) of my K50.

S= silver, B=black
Hopefully this (partially) answers your question ?

Regarding G4:

@MarkCole

All new K Series are as the pics on-site, easiest way to tell is isolation footers, if the device has them, then it is the latest G4 Series.

@MarkCole

It’s quite simple, they have G4 in the serial number
All G4 OLADRA and K50 have Earth posts as a simple visual check.
Likewise no FUSE on the IEC inlet for all G4 models.
