Schneider Electric P342020
This is a CPU module from Schneider’s M340 series.
It is a P34 2020 type PLC CPU.
This module consists of 2 PCBs. I named them power supply board and CPU board.
The PCB are well designed, multi layer ones, as can be seen, the assembly is high quality.
The processing power comes from the Atmel AT91RM9200 32 bit ARM processor.
Unfortunately I haven’t managed to figure out what is the actual type of the 2 ICs under the processor (the 2 pieces of “IEG47 D9FJB”).
Additional to the careful PCb design the module has a steel shielding around the 2 PBCs, which makes it even more noiseless and more protected from EMI.
