The 6ES7241-1AA22-0XA0: Isolation is tested at 1500 V AC between telephone cable and logic/field side, and 500 V AC between field side and logic. That matters when the modem line runs through a plant with ground potential differences. The 24 V supply range is 20.4 to 28.8 V DC, so standard industrial power rails work.
Listed width is 71.2 mm.
Depth is 62 mm.
