Product details

Rated for 120/230V AC output loads

The 6ES7322-1HF00-0AA0: The module switches loads at a rated AC voltage of 120/230V AC, with a permissible range of 79V to 264V AC. That covers nominal 110V and 220V line supplies across most industrial regions without needing a different module variant.

20-pin front connector — panel wiring

Connection requires a 20-pin front connector (ordered separately). The module snaps onto the S7-300 DIN rail and connects to the backplane bus via the standard S7-300 connector interface.
