Siemens 6ES7 322-1BL00-0AA0 Simatic S7 Module

Siemens 6ES7-322-1BL00-0AA0 SIMATIC S7-300 Digital Output Module SM 322 provides 32 isolated DC 24 V outputs rated at 0.5 A per channel. It is designed for SIMATIC S7-300 and ET 200M distributed I/O configurations and mounts in a standard S7-300 rack, interfacing via a single 40-pole backplane connector. The outputs are organized into four banks of eight channels, which simplifies wiring and current budgeting across the module. Each channel switches 24 V DC up to 0.5 A; the module supports 4 A per group and 16 A total across all outputs. Typical applications include driving DC actuators such as solenoids, relays, and indicator devices in industrial automation, where compact, centralized output expansion is needed. When integrating this SM 322 module, verify compatibility with your CPU, backplane, and firmware version, and plan the wiring and protection for multiple 24 V loads to ensure reliable operation within the module’s electrical limits.
