Description
The Siemens 6ES7322-1BH01-0AA0 is the 16-channel SM 322 digital output module, 24 V DC at 0.5 A per output, isolated, with a total current of 4 A per group and 8 A per module 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: Digital output module
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7322-1BH01-0AA0 used for?
It switches relays, solenoid valves, contactor coils and lamps from an S7-300 CPU, in the CPU's rack or an ET 200M station.
Key features
- 16 digital outputs, 24 V DC, 0.5 A each
- Total current 4 A per group, 8 A per module
- Isolated
- 20-pin front connector
- Discontinued by Siemens on 1 October 2025; spare part only
