If your application demands very stable analog I/Os you
should choose a linear power supply instead of a switching
power source for the CPU. Always place the power supply as

short as possible and avoid running it along side high current
cable in the same cable conduit. The T100MD-2424+ PLC
will be reset when the power supply voltage dips
