8 AC outputs at line voltage
The Siemens 6ES7322-1FF00-0AA0 is an SM 322 digital output module providing 8 AC outputs rated at 1A per channel, with optical isolation between the backplane and field wiring. This module switches loads directly at mains voltage — think contactor coils, solenoid valves, or indicator lamps in a 120V or 230V AC control circuit — without an interposing relay.
Lifecycle: end-of-line sourcing
No official replacement order code is recorded for the 6ES7322-1FF00-0AA0, so a direct form-fit-function swap from Siemens is not documented.
The 8 AC outputs are optically isolated from the backplane, so a short on the field side does not take down the CPU or adjacent modules. Wiring is to the front-pin connector (screw-terminal type typical for SM 322); each output is rated 1A continuous, resistive or inductive load.
