Siemens 6ES7223-1BH22-0XA0 is a SIMATIC S7-200 digital I/O EM 223 expansion module designed exclusively for S7-22X CPUs. It provides eight 24 V DC digital inputs (8 DI) and eight 24 V DC digital outputs (8 DO), with a per‑channel current rating of 0.75 A for the outputs. The module operates on 24 V DC, with a permissible input range of roughly 20.4 to 28.8 V DC, and is offered as a spare part for S7-22X installations. This configuration enables compact, high‑density digital I/O in SIMATIC S7-200 projects, ideal for interfacing sensors and actuators in automation tasks.
