Product Overview
The Siemens SIMATIC S7-200 CPU 221 Compact (6ES7211-0AA23-0XB0) is a micro PLC in the S7-200 family, providing 6 digital inputs and 4 digital outputs with integrated program and data memory. It functions as a standalone controller in compact automation tasks such as small machine control, sequential logic, and encoder interfacing. With built-in MPI/PPI serial communications and high-speed counting, it is designed for localized control on machines or modular systems requiring CPU-level logic processing.
Best Suited For
- Small machine control (stand-alone applications)
- Sequential logic and timing tasks
- High-speed counting or pulse output up to 20 kHz
- Encoder interface via 2-wire sensors
