About the Siemens 6ES7322-1BL00-0AA0
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.
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.
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 40-pin front connector with the field wiring normally moves across to the replacement.
