The Siemens SIMATIC S7-200 CN CPU 224XP PLC (6ES7214-2BD23-0XB8) is a compact programmable logic controller designed for industrial automation, machine control, and process monitoring. This CPU combines an AC power supply with integrated digital and analog I/O, providing a practical control solution for compatible industrial machinery and legacy automation systems.

The CPU 224XP CN features 14 digital DC inputs, 10 relay outputs, two integrated analog inputs, and one analog output. This combination enables the controller to process digital signals from switches and sensors, monitor compatible analog instruments, and control connected equipment according to the programmed logic.

Two PPI/user-programmable communication interfaces support connections to compatible programming devices, operator interfaces, and other supported industrial equipment. The controller also supports compatible S7-200 expansion modules, high-speed counter functions, and additional communication options through suitable hardware.

This model is part of the Siemens SIMATIC S7-200 CN regional product family. It is a legacy product and the manufacturer documentation identifies it as a spare part with CE approval only. Buyers should confirm the exact regional version, programming compatibility, and installation requirements before purchasing.
