Description
The Siemens 6ES7322-1HH01-0AA0 is the SM 322 relay output module with 16 isolated relay contacts. Siemens's data sheet gives a rated output current of 2 A, load voltages up to 230 V AC or 120 V DC, a lamp load of up to 50 W at 230 V AC, and a 20-pin front connector. Siemens's data sheet marks it as a spare part. Siemens names no direct successor for the order number; its route forward is migration to the S7-1500 with ET 200MP.
Application: Relay output module
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7322-1HH01-0AA0 used for?
It switches loads that a 24 V transistor output cannot: 230 V AC coils, other voltage levels, and circuits that need galvanic separation from the PLC.
Key features
- 16 relay outputs
- Rated output current 2 A
- Load voltage up to 230 V AC or 120 V DC
- Lamp load up to 50 W at 230 V AC
- 20-pin front connector
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7322-1HH01-0AA0 discontinued?
Yes. Its manufacturer lifecycle status is Discontinued.
Can another Siemens SIMATIC S7-300 part replace it?
Potential replacements must be checked against the required ratings, dimensions and connections. Sharing a family name does not establish interchangeability.
Do you ship worldwide?
Yes. TimControls ships worldwide. Parts usually ship within 3 to 7 working days of order confirmation, and the exact lead time and shipping options are stated on your quote. Include your delivery country and postal code when you ask for a quote.
