Siemens SIMATIC S7-300 Digital Output Module SM 322, 6ES7322-1BL00-0AA0, provides 32 DC 24 V digital output points for the S7-300 PLC system. Each output switches up to 0.5 A at 24 V DC, and the channels are optically isolated in four groups, with a group total of 4 A (16 A per module) and a single 40‑pole interface (1x 40‑pin). Designed to drive loads such as relays, contactors, solenoids, or indicator devices, the SM 322 is a compact, modular I/O option for distributed control in Siemens automation installations.
