  Product Description:
  6ES7223-0BD30-0XB0 is a SIMATIC S7-1200 SB1223 digital signal board providing 2 digital inputs and 2 digital transistor outputs (24 V DC). The board plugs directly into the front signal-board slot of the S7-1200 CPU, allowing additional I/O expansion without occupying extra DIN-rail space.

  Key Features

  • 2 × Digital Inputs (24 V DC)

  • 2 × Digital Outputs (transistor, 0.5 A)

  • Compact signal board expansion (inside CPU)

  • LED diagnostics for input/output status

  • Configurable in TIA Portal

  Typical Applications

  • Small automation systems

  • Machine control panels

  • Pump or valve control

  • Additional I/O when the CPU integrated I/O is insufficient
