About the Siemens 6ES7322-1BF01-0AA0
The Siemens 6ES7322-1BF01-0AA0 is the high-current SM 322: 8 outputs at 2 A each, where the 6ES7322-8BF00-0AB0 gives 8 outputs at 0.5 A with diagnostics. Siemens's data sheet gives a 24 V DC load voltage (20.4 to 28.8 V), electronic short-circuit protection, two groups of 4 outputs at up to 4 A per group, and no diagnostics. Siemens's data sheet marks it as a spare part.
What is the 6ES7322-1BF01-0AA0 used for?
It switches 24 V DC loads of up to 2 A, such as valves, contactor coils and lamps, from an S7-300 CPU.
Lifecycle and successor
Discontinued.
Before you order
