Siemens 6ES7 322-1BL00-0AA0 Digital Output Module

Siemens 6ES7 322-1BL00-0AA0 is a SIMATIC S7-300 SM322 digital output module that provides 32 isolated 24 V DC outputs, with each channel rated for 0.5 A. It plugs into a S7-300 backplane via a 40‑pole interface, delivering compact, scalable I/O expansion for industrial control cabinets. The isolated per-channel outputs help protect the controller and backplane while driving low‑current loads such as solenoids, relays, indicator devices, and other 24 VDC actuators. This model is described as 32 DO, 24 V DC/0.5 A, with eight groups of outputs to simplify wiring and current distribution in multi-channel installations, making it well suited for distributed automation tasks in machinery and panel applications.
