Key Product Information

Technical Data Summary

Digital Load Control and Channel Grouping

The SM 522 module provides sixteen 24 V DC digital output channels for compatible SIMATIC S7-1500 stations. Channels are organized in groups of eight, so supply segmentation, group current and load wiring must be checked during design or replacement. The included push-in front connector supports field connection preparation for the specified module.
