    AI Overview
    The Siemens SIMATIC S7-1200 SM 1221 (6ES7223-1BL30-0XB0) refers to a digital input signal module designed to expand the input capacity of the S7-1200 PLC system. It converts external 24V DC signals from sensors, switches, and proximity devices into the internal signal level for the CPU. 
    Note: While the prompt mentions 6ES7223-1BL30-0XB0 (typically an SM 1223 DI/DQ), search results indicate the SM 1221 family specifically represents DI-only modules, with 16-channel versions typically being 6ES7221-1BH32-0XB0. 
    Key Features 
    • Channels: 16 Digital Inputs (24V DC).
    • Signal Type: Sink/Source (IEC 61131 Type 1).
    • Diagnostics: Integrated LED diagnostics for channel status.
    • Installation: Mounts on a DIN rail directly to the right of the CPU.
    • Isolation: Potential separation between channels and the backplane bus. 
    Technical Specifications 
    • Supply Voltage:
      24
      V DC
       (
      20.4
      V
       to
      28.8
      V
      ).
    • Input Current: Typically
      6
      mA
       per channel.
    • Cable Length: Maximum
      500
      m
       (shielded) or
      300
      m
       (unshielded).
    • Protection Rating: IP20.
    • Operating Temperature:
      −20
      °C
       to
      60
      °C
      .
    • Dimensions: Approximately
      45
      mm
       width.       
    Common Applications 
    • Connecting 24V DC sensors.
    • Integrating proximity switches and pushbuttons.
    • Machine automation and panel manufacturing. 
    If you can confirm whether you need the 16-input (SM 1221) or 16-input/16-output (SM 1223) version, I can provide the exact wiring diagram.

    What is the difference between Siemens S7-200 smart and S7-1200?
    Next, let's compare the processing power and performance of these two PLCs. The S7-200 smart uses a 32-bit CPU with a maximum operating frequency of 40 MHz and a lower processing speed. The S7-1200 uses a higher-performance CPU with a maximum operating frequency of 500 MHz and a faster processing speed.
