6ES7223-1PL32-0XB0 - Siemens S7-1200 IO 16DI/16DO Relay

Belonging to the SM 1223 digital input/output module family, the 6ES7223-1PL32-0XB0 offers 16 digital inputs (24V DC, sink/source) and 16 relay outputs rated at 2 A per channel—making it ideal for automation applications that require electrical isolation and control of high-power loads. The module’s compact form, measuring 8.80 x 11.00 x 8.50 cm with a net weight of 0.319 kg, is optimized for dense panel layouts and machine-level integration.

With PM300: Active Product Lifecycle classification, this Siemens PLC ensures long-term support and firmware compatibility across evolving automation setups. Manufactured in Germany, it meets strict Siemens engineering standards, providing high durability, precise signal handling, and seamless integration into the S7-1200 platform via TIA Portal. The relay outputs offer galvanic isolation and quiet switching, making the unit suitable for inductive loads and environments prone to electrical noise.

For engineers building centralized or distributed control panels, the 6ES7223-1PL32-0XB0 simplifies wiring and reduces the need for expansion modules—offering all essential I/O functionality in a single, reliable module. For full technical specifications, wiring diagrams, and environmental details, refer to the official Siemens datasheet for 6ES7223-1PL32-0XB0.

The Siemens 6ES7223-1PL32-0XB0 PLC is widely adopted in applications where both input acquisition and output actuation must be handled within a compact, unified module. It is ideal for conveyor logic control, packaging systems, and multi-signal automation tasks such as material sorting, where fast input detection must drive reliable relay-based output control.

Each of the 16 relay outputs is capable of switching solenoids, motors, contactors, indicator lights, and alarms—without needing external interposing relays. This not only reduces panel complexity and cost but also enhances system response time. Maintenance engineers benefit from simplified diagnostics through onboard LEDs and TIA Portal integration, allowing quick fault isolation and process recovery.

It is especially suitable for educational labs and training panels, offering clear wiring access and an intuitive I/O layout. Whether for upgrading legacy systems or powering new industrial machines, this PLC module offers the scalability, safety, and Siemens-grade reliability needed for modern automation. For students and junior engineers, the 6ES7223-1PL32-0XB0 offers valuable hands-on experience with real-world control systems that involve both digital inputs and mechanical relay switching.
