Description
The Siemens 6ES7322-1BL00-0AA0 is the SM 322 digital output module with 32 outputs at 24 V DC and 0.5 A. Siemens's data sheet gives electronic short-circuit protection, a switching frequency up to 100 Hz with resistive load, a total current of 4 A per group and 16 A per module, and a 40-pin front connector for the field wiring. 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.
Application: Digital output module
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7322-1BL00-0AA0 used for?
It switches relays, solenoid valves, contactor coils and indicator lamps from an S7-300 CPU, in the CPU's rack or an ET 200M remote station.
Key features
- 32 digital outputs, 24 V DC, 0.5 A each
- Electronic short-circuit protection
- Up to 100 Hz with resistive load
- Isolated, 4 A per group, 16 A per module
- 40-pin front connector
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7322-1BL00-0AA0 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.
