About the Siemens 6ES7322-1FH00-0AA0

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.

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.

Lifecycle and successor

Discontinued: product cancellation (Siemens SiePortal), spare part only.

Before you order

What to photograph or confirm so the right unit is quoted.

Check the order number on the module. The front connector with the field wiring normally moves across to the replacement.
