6ES7223-1BL32-0XB0 Siemens SIMATIC S7-1200 Digital I/O SM 1223 16 DI 24 V DC
The Siemens 6ES7223-1BL32-0XB0 is a high-performance digital input/output (I/O) expansion module for the SIMATIC S7-1200 programmable logic controller (PLC) system. Designed for industrial automation applications requiring reliable and flexible signal handling, this compact module provides 16 digital inputs and 16 digital outputs, all operating at 24 V DC, with support for both sinking (NPN) and sourcing (PNP) wiring configurations—making it compatible with a wide range of sensors, switches, actuators, and control devices worldwide.
As part of the globally trusted S7-1200 family, the 6ES7223-1BL32-0XB0 integrates seamlessly into TIA Portal (Totally Integrated Automation Portal) for fast engineering, diagnostics, and commissioning. It features screw-type terminal blocks for secure wiring, built-in electrical isolation between field circuits and the backplane, and robust protection against overvoltage, reverse polarity, and short circuits. With a compact width of just 40 mm, it conserves valuable panel space while delivering industrial-grade reliability in environments ranging from manufacturing and packaging to water treatment and building automation.
