Role in the SIMATIC S7 / PCS 7 architecture

6ES7322-8BH01-0AB0 is the Siemens order number for a diagnostics-capable SM 322 digital output module. It provides 16 outputs for 24 V DC loads and is intended for configurations using an IM 153-2 interface.

16 diagnostic outputsSixteen 24 V DC channels with a nominal output current of 0.5 A per channel.
Wire-break monitoringSiemens specifies wire-break detection for both 0 and 1 signal states.
40-pole connectionThe module uses one 40-pole front connection and requires the IM 153-2 interface.
Electronic short-circuit protectionThe Siemens manual states electronic protection with a typical response threshold of 1.4 A.
