6ES7223-1BL22-0XA8 SIEMENS SIMATIC S7-1200 Digital Input/Output Hybrid Module
The Siemens SIMATIC S7-1200 digital Hybrid I/O module 6ES7223-1BL22-0XA8 is a high-performance expansion unit specially designed for leak type (NPN) signal systems, integrating 8 digital input channels and 8 digital output channels. All adopt leakage type (NPN) wiring. This module is widely used in automation equipment mainly composed of Japanese, Korean or some domestic sensors and actuators, and is particularly suitable for small and medium-sized control systems that require unified low-level effective logic, high-speed response and compact installation.
