Siemens 6ES7322-1BL00-0AA0 Digital Output Module

The Siemens 6ES7322-1BL00-0AA0 is a SIMATIC S7-300 digital output module (SM 322) that provides 32 isolated DC outputs at 24 V, each rated for 0.5 A, enabling reliable, independently isolated switching of 24 V loads from a single S7-300 backplane. The module connects to the backplane via a single 40-pole interface and supports a total module current of up to 16 A, with a per-group limit of 4 A, reflecting the SM322 family’s load-distribution design. With 32 channels, this SM322 module is suitable for applications such as driving relays, contactors, solenoids, and indicator devices in industrial automation, providing galvanically isolated outputs and straightforward integration with Siemens software for scalable, modular control in compact control cabinets.
