Description
The Siemens 6ES7322-1FH00-0AA0 is the SM 322 digital output module for 120/230 V AC loads, 16 isolated outputs at 1 A each. Siemens's data sheet derates the output current to 0.5 A between 40 and 60 °C and gives 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: Digital I/O module
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7322-1FH00-0AA0 used for?
It switches mains-voltage loads, such as 230 V AC contactor coils, solenoids and lamps, directly from an S7-300.
Key features
- 16 digital outputs, 120/230 V AC
- 1 A per output (0.5 A at 40-60 °C)
- Isolated
- 20-pin front connector
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7322-1FH00-0AA0 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.
