EM 223 24 VDC digital I/O module is a new digital I/O expansion module launched by Siemens. The module has 32 inputs and 32 outputs, and supports 24 VDC and 250 VAC voltage input, which can meet the needs of different applications.
The Siemens EM 223 is a digital expansion module designed for S7-200 programmable controller systems. It offers two configurations: one with solid-state (MOSFET) outputs and another with relay outputs, both operating at 24 VDC input voltage.
Key specifications include physical dimensions of 196 mm x 80 mm x 62 mm and a weight ranging from 500g to 580g. The module supports up to 32 inputs (sinking or sourcing) and 32 outputs, with specific electrical ratings for voltage, current, and isolation provided in the text. This manual is written in Chinese.
