Siemens 6ES7 322-1BF01-0AA0 Digital Output Module

Siemens 6ES7322-1BF01-0AA0 SM322 Digital Output Module delivers eight isolated 24 V DC outputs for SIMATIC S7-300 controllers. Each of the eight outputs is rated for 2 A, enabling direct switching of DC loads such as relays, contactors, solenoids, or indicator lamps while maintaining optical isolation from the controller for improved noise immunity and protection. The module uses a 20-pin backplane interface to plug into an S7-300 I/O rack, forming a compact, scalable solution for expanding discrete output channels in 24 V DC signaling environments. As part of the SM322 family, it supports standard Siemens diagnostics and hardware configuration through the familiar S7-300 programming model, making it suitable for factory automation, packaging lines, conveyors, and general machine control where multiple DC outputs are required in a single eight-channel module.
