6ES7223-1BL32-0XB0 SM 1223 16DI/16DO Digital I/O Module 24V DC | Siemens

The Original New Siemens 6ES7223-1BL32-0XB0 SIMATIC S7-1200 SM 1223 Digital I/O Module is a high-density signal module designed for efficient I/O expansion in S7-1200 automation systems. It combines 16 digital inputs (24V DC, sink/source configurable) and 16 transistor outputs (0.5A per channel, sourcing) in a single module, providing 32 I/O points in a compact 70 mm width. Fully compatible with all S7-1200 CPUs (except CPU 1211C).

Core Engineering Highlights:
16 digital inputs (24V DC, sink/source) | 16 transistor outputs (24V DC, 0.5A, sourcing) | 0.1 ms / 1.0 ms output delay | Configurable input filter: 0.2–12.8 ms | 125 mA backplane bus current | 2.5 W power loss | 24V DC supply | IP20 protection | –20°C to +60°C operating
