Front connector is 20-pin – not included, factor that into your BOM. ## Ratings that drive the selection Thermal continuous current per relay is 2 A. Inductive load max is 2 A, with 100 000 cycles at 230 V AC and 700 000 cycles at 120 V AC. No diagnostics, no short-circuit protection, no wire-break detection. It's a simple relay board – no fancy alarms. That means you need external fusing or a suitable load circuit if fault protection matters. Isolation tested at 1 500 V AC between channels and groups of 8. That's solid for panel separation but watch the group isolation if mixing power domains. ## Where this part fits Drops into any standard S7-300 rack – same 40 mm width, 125 mm height, 120 mm depth. No fieldbus or CPU compatibility issue; it's just a relay output slice. Unshielded cable runs up to 600 m, shielded up to 1 000 m. Connects via a 20-pin front connector (not included). Reuse the existing connector when replacing a module.","metaTitle":"Siemens 6ES7322-1HH01-0AA0 S7-300 16DO Relay, EOL Sourced","metaDescription":"16 relay outputs, 2A per channel, 230VAC/24VDC.
