Key Product Information

Technical Data Summary

Compact I/O Expansion for S7-1200

This SB 1223 installs as a compact signal-board expansion for compatible SIMATIC S7-1200 controllers. Its two digital inputs receive 24 V DC field states, while two digital outputs provide 24 V DC switching channels. It is intended for applications that need a small I/O increase without selecting a larger external signal module.

Features and Procurement Notes

• Adds two 24 V DC digital input points.
• Adds two 24 V DC digital output points.
• Compact signal-board construction for compatible S7-1200 CPUs.
• Supports targeted replacement or limited machine I/O expansion.
• Requires confirmation of CPU, slot, wiring and project configuration.

Applications

• Adding a small number of sensor and actuator signals to a compatible S7-1200 CPU.
• Replacing an installed SB 1223 after exact part-number and wiring checks.
• Supporting compact machine-control modifications with limited extra digital I/O.
• Separating a minor I/O expansion from larger external module changes.
