About the Siemens 6ES7322-1HF10-0AA0
The Siemens 6ES7322-1HF10-0AA0 is the 5 A relay version of the SM 322: unlike the 2 A 6ES7322-1HF01-0AA0 with its 20-pole connector, it has 8 relays isolated channel by channel, rated at 5 A, and takes a 40-pole front connector. Siemens's data sheet gives the relay coils a 24 V DC supply and leaves short-circuit protection to an external fuse, and names the spring-loaded 6ES7392-1BM01-0AA0 as a front connector it can use. Siemens's data sheet marks it as a spare part.
What is the 6ES7322-1HF10-0AA0 used for?
It switches loads at 24 V DC or 230 V AC from an S7-300 CPU through relay contacts, each output on its own circuit.
Lifecycle and successor
Discontinued.
Before you order
What to photograph or confirm so the right unit is quoted.
Check the order number and the front connector: the 1HF10 takes a 40-pin front connector, the 1HF01 a 20-pin one.
Other parts in the Siemens SIMATIC S7-300 family
Listed for reference. They differ from the 6ES7322-1HF10-0AA0 in rating, supply, interface or function and are not interchangeable with it unless Siemens says so. Match the part number on your unit.
