Siemens 6ES7223-1BH32-0XB0 Digital Input Output Module

Siemens 6ES7223-1BH32-0XB0 SM 1223 digital input/output module expands a SIMATIC S7-1200 controller by adding eight digital inputs and eight transistor outputs, all operating at 24 V DC, ideal for increasing discrete I/O capacity in compact automation cabinets. The module supports both sinking and sourcing output configurations, so the eight DO channels can switch DC loads up to 0.5 A per channel, enabling direct control of sensors, indicators, and small actuators from a single, unified 24 V DC I/O bus. As part of the SM 1223 family, it interfaces with the S7-1200 backplane and is configured within Siemens STEP 7 or TIA Portal, aligning with the SIMATIC real-time I/O framework and cataloged options for scalable plant automation. This 8 DI / 8 DO digital I/O module is designed for reliable, modular expansion of a PLC system, offering a compact footprint for machine control panels, packaging lines, and other automated processes where discrete input signals and straightforward output control are required.
