Product Overview

The 6ES7221-1BH32-0XB0 is a SIMATIC S7-1200 SM 1221 digital input module by Siemens, providing 16 standard digital inputs at 24 V DC with sink/source configuration. It integrates into the S7-1200 modular controller platform, enabling expansion of input channels for machine and process automation systems. In control architectures, it serves as a remote I/O extension, typically deployed in manufacturing lines, small machine control, packaging systems, and OEM equipment where additional discrete signal inputs are required. 6ES7221-1BH32-0XB0 supports interrupt-capable inputs with configurable input delay parameters.
