Siemens S7-200 Programmable Logic Controller Module

Siemens SIMATIC S7-200 CPU 226 Compact unit, powered by 24 V DC, delivers 24 digital inputs and 16 digital outputs, making it a compact micro PLC suited for small‑footprint automation tasks. It carries 16/24 KB of program memory, providing a compact but capable space for straightforward control logic, timers, and counters in simple machines and packaging lines. As part of the S7-200 family, this CPU supports expansion via EM-series modules to grow I/O and functionality when the project demands more capability, for example EM231/EM235 expansion options. The 24 V DC power architecture integrates with standard industrial sensors and actuators, enabling reliable stand‑alone control or integration with basic remote I/O configurations. Typical applications include small machines, conveyor sections, and standalone automation tasks where a compact, easy‑to‑program controller is advantageous and where robust, Siemens‑brand hardware and compatibility with the S7‑200 ecosystem are valued.
