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

Siemens 6ES7 322-1BF01-0AA0 Digital Output Module (SM322) for SIMATIC S7-300 provides eight 24 V DC digital outputs, each capable of switching up to 2 A. Outputs are optically isolated from the backplane to protect the controller, and the module groups its channels into four groups to simplify wiring and fault isolation. The 1x 20-pole interface and standard S7-300 rack form factor enable straightforward integration as an I/O expansion for DC load switching, relays, actuators, and indicator devices in automation panels. Designed for robust industrial use, this module supports reliable DC switching within a modular SIMATIC system and is compatible with the broader SIMATIC S7-300 ecosystem.
