This module is compatible only with S7-22X CPUs in the S7-200 CN family; it will not fit the standard S7-200 or S7-1200/1500 racks. The 32-input block handles both sink and source field wiring, while the 32-output block sources current at 0.75 A per channel — enough for small contactors, indicator banks, or valve solenoids without external interposing relays. ## Current lifecycle and sourcing posture Listed as current lifecycle stage, but described as a spare part — this means the module is not intended for new machine designs. It is held for existing S7-200 CN installations that need a drop-in replacement for a failed or expanded I/O bank. ## Power draw and mechanical fit Typical power loss is 9 W — the module draws that from the backplane regardless of output load, so budget the 24 V DC supply rail accordingly. The 62 mm depth, 196 mm width, and 80 mm height match the standard S7-200 CN expansion footprint; it sits on the DIN rail and connects via the ribbon-bus to the CPU. Each output channel draws 4 mA for the signal '1' state (the internal logic current), and the rated output current is 750 mA per channel — derate if all 32 outputs are on simultaneously, as the total 24 A would exceed the module's internal bus capacity. Practical use typically limits simultaneous loading to 8–16 outputs at full current.","metaTitle":"Siemens 6ES7223-1BM22-0XA8 EM 223, 32 DI / 32 DO, 0.75 A","metaDescription":"Siemens 6ES7223-1BM22-0XA8 SIMATIC S7-200 CN EM 223 digital I/O module, 32 inputs 24 V DC, 32 outputs 24 V DC, 0.75 A/channel.
