6ES7223-1BM22-0XA8 SIEMENS SIMATIC S7-1200 Digital Input/Output Hybrid Module
The Siemens SIMATIC S7-1200 digital Hybrid I/O module 6ES7223-1BM22-0XA8 is a high-performance and highly integrated expansion unit that integrates 8 digital input channels (DI) and 8 digital output channels (DO), all using source type (PNP) wiring. Designed specifically for small and medium-sized automation systems that require high-speed response, reliable signal processing and compact installation. As a classic general-purpose hybrid module in the S7-1200 series, it is widely applied in fields such as equipment control, production line monitoring, and mechanical automation.
