Siemens 6ES7223-1PL00-0XA0 Digital Input Module

Siemens 6ES7223-1PL00-0XA0 is a SIMATIC S7-200 EM223 digital input module that provides 16 digital input channels at 24 V DC for expanding a S7-200 CPU’s sensing capability. Designed for the S7-21X family, this EM223 digital I/O block is intended to read signals from common 24 V sensors and switches, such as pushbuttons, limit switches, and simple proximity sensors, enabling straightforward digital input reading in compact automation projects. The part number 6ES7223-1PL00-0XA0 uniquely identifies this 16-channel digital input module within Siemens’ S7-200 EM223 lineup, and distributor listings frequently note its use with S7-21X CPUs. Typical use cases include machine control panels, conveyor sensing, and panel-level I/O expansions where 24 V digital inputs are required. In practice, 16 DI channels at 24 V DC integrate into the SIMATIC S7-200 ecosystem as a dedicated digital input expansion option, offering a simple path to scale input points without altering the core CPU configuration.
