Siemens 6ES7223-1BH00-0XA0 Digital Input Module

Siemens 6ES7223-1BH00-0XA0 is an EM223 digital input/output expansion module for the SIMATIC S7-200 family, designed to attach to an S7-21X CPU to add I/O capability. It provides 8 digital inputs and 8 digital outputs, all rated for 24 V DC operation, so you can connect standard 24 V sensors and 24 V actuators directly. The part number identifies the EM223 8DI/8DO configuration and the module is intended for use with S7-21X CPUs, expanding small- to mid-size machine control applications that require additional digital I/O without changing the central controller. Typical uses include basic machine controls, signaling, interlocking, and simple automation tasks in packaging lines or equipment where compact digital I/O expansion is needed. The EM223 communicates via the S7-200 backplane system and integrates with existing S7-200 installations, delivering a straightforward expansion path for digital I/O with Siemens' SIMATIC hardware.
