It provides 32 digital inputs and 32 digital outputs, all operating at 24 V DC, in a single unit that snaps onto the S7-200 rail alongside the CPU. Each output channel is rated for 0.75 A resistive or inductive load, with a group limit of 10 A per 16-output group. The module draws up to 240 mA from the 5 V DC backplane bus and up to 128 mA from the external 24 V supply (4 mA per active input). ## Input and output characteristics Inputs accept 24 V DC sink/source wiring with a signal \"1\" threshold of 15 V to 30 V DC (typical 4 mA at 24 V). The input filter delays the rising edge by up to 4.5 ms, which filters out contact bounce but also sets the minimum detectable pulse width for fast-counting applications. Outputs are rated 0.75 A per channel with inductive shutdown clamped to L+ (-48 V). The module includes optocoupler isolation between the backplane and the I/O circuits, tested at 500 V AC. Plug-in I/O terminals simplify field wiring replacement without removing the module from the rail. Typical power loss is 9 W, which should be factored into the enclosure thermal budget, especially when all 32 outputs are loaded near the 0.75 A per-channel limit. This module carries a current lifecycle stage, meaning it remains in the Siemens portfolio as a spare part for the S7-200 platform. The S7-200 family is a mature product line, and this EM 223 is intended for maintenance and replacement of existing installations rather than new system designs.","metaTitle":"Siemens 6ES7223-1BM22-0XA0 S7-200 EM 223, 32DI/32DO","metaDescription":"Siemens 6ES7223-1BM22-0XA0 spare-part SIMATIC S7-200 EM 223, 32 digital inputs 24 V DC, 32 digital outputs 24 V DC, 0.75 A/channel.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC I/O & Expansion Modules"],"specifications":{"Depth":"62 mm","Width":"196 mm","title":"6ES7223-1BM22-0XA0","Height":"80 mm","description":"***Spare part*** SIMATIC S7-200, Digital I/O EM 223, only for S7-22X CPU, 32DI 24 V DC, Sink/Source, 32DO 24 V DC; 0.75 A/channel, SOURC","2-Wire Sensor":"Yes","For Signal \"0\"":"0 to 5 V","For Signal \"1\"":"15 V DC to 30 V DC","Shielded, Max.":"500 m","Weight, approx.":"500 g","lifecycle_stage":"current","Power loss, typ.":"9 W","Rated value (DC)":"24 V","Unshielded, Max.":"150 m","On Lamp Load, Max.":"5 W","At \"0\" To \"1\", Max.":"4.5 ms","For Signal \"0\", Max.":"0.1 V","For Signal \"1\", Min.":"20 V","For Signal \"1\", Typ.":"4 mA","Isolation tested with":"500 V AC","Plug-in I/O terminals":"Yes","Type of input voltage":"DC","Number of digital inputs":"32","Short-circuit protection":"No","Number of digital outputs":"32","With Inductive Load, Max.":"0.75 A; each output","With Resistive Load, Max.":"0.75 A; each output","For Signal \"1\" Rated Value":"750 mA","from backplane bus 5 V DC, max.":"240 mA","Current per conductor/group, max.":"0.75 A; 10 A per group","Between The Channels, In Groups Of":"16; 2 groups with 16 outputs each","Potential separation digital inputs":"Yes; Optocoupler","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","Potential separation digital outputs":"Yes; Optocoupler","from external supply (24 V DC), max.":"128 mA; ON: 4 mA/input","Limitation of inductive shutdown voltage to":"L+ (-48 V)","Permissible Quiescent Current (2-Wire Sensor), Max.":"1 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$647.00 – $691.52","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/4244e6711ca4776ca4f58c20846e85d2.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=415233&mlfb=6ES7223-1BM22-0XA0"},"ai":{"faq":[{"question":"What is the output current rating per channel on this EM 223 module?","answer":"Each digital output is rated 0.75 A maximum for both resistive and inductive loads.
