The Siemens 6ES7223-1BL32-0XB0 is a digital I/O signal module from the SIMATIC S7-1200 product family, designated as SM 1223. This module provides 16 digital inputs and 16 digital outputs in a compact form factor, enabling flexible expansion of S7-1200 PLCs. The 16 inputs accept 24 V DC signals with Sink/Source capability, while the 16 outputs are transistor-based with 0.5 A switching capacity per channel. The module operates with a rated supply voltage of 24 V DC and features IP20 protection rating, making it suitable for industrial control cabinet installations. It supports parameterizable input delays and includes short-circuit protection for outputs. The module connects to the S7-1200 controller via backplane bus and uses front connector terminals for field wiring.
