Siemens 6ES7214-2AD23-0XB0 Programmable Logic Controller

The Siemens 6ES7214-2AD23-0XB0 is a SIMATIC S7-200 CPU 224XP Compact Unit designed for DC-powered automation tasks in small to medium control panels. It combines 14 digital inputs (DC 24 V) and 10 digital outputs (DC 24 V) with 2 analog inputs and 1 analog output, all housed in a single compact module and powered from 24 V DC. The controller offers code memory of 12–16 KB and data memory of 10 KB, along with two PPI/FREEPORT ports for serial communication with HMIs, other PLCs, or field devices. It supports up to seven expansion modules, enabling scalable I/O and feature additions within the S7-200 family. Typical applications include discrete machine control, simple conveyors, and packaging or small process tasks where a compact, field-bus-capable controller is suitable. Power characteristics list a current draw up to 900 mA at 24 V DC, with peak inrush currents up to about 12 A during power-up. As a CPU 224XP variant, it provides reliable performance for straightforward automation logic, straightforward programming, and compatibility with existing S7-200 tooling and configurations, making it a common spare-part choice in Siemens distributor catalogs and technician-maintained installations.
