Siemens 322-1BL00-0AA0 Digital Output Module PLC

The Siemens SIMATIC S7-300 SM322 digital output module, part number 6ES7322-1BL00-0AA0, provides 32 DC 24 V outputs at 0.5 A per channel, enabling reliable control of multiple 24 V loads from an S7-300 controller while incorporating electrical isolation between the outputs and the controller to help protect the control system in industrial environments. The module uses a 1x 40-pole interface for mounting in S7-300 backplanes and carries a total current rating of 4 A per group (16 A per module), ensuring many outputs can be energized simultaneously without overloading the device. The 6ES7322-1BL00-0AA0 designation identifies the SM322 digital output module within the SIMATIC S7-300 family, delivering 32 DO at 24 V DC with 0.5 A per output and is widely documented on Siemens' official channels as part of the S7-300 ecosystem; this precise model is commonly listed in Siemens Industry Mall product catalogs and accompanying data sheets with the same specifications.
