The 38.4 kbit/s ceiling is the same for ASCII, 3964(R), and printer-driver modes; if your device expects 115.2 kbit/s, this part won't keep up. Operating range is 0 °C to 70 °C, which covers most control-room environments but not unheated cabinets in northern winters. The 25 mm width (one slot) and 290 mm height are standard S7-400 form factor — it slots into any CR/UR rack without crowding adjacent modules. This is a serial gateway for the S7-400 rack — it lives in the central or expansion rack, addressed via the STEP 7 configuration package included on CD. The single RS-232/422 port connects to printers or serial instruments; there's no second channel for daisy-chaining. Memory consumption on the CPU memory card runs 1 to 5 KB for parameters plus 0 to 55 KB for message texts, so factor that into your CPU memory budget. The module is not reloadable with customer-specific drivers — you're limited to the built-in protocol stack.","metaTitle":"Siemens 6ES7441-1AA04-0AE0 CP 441-1, 1-channel, 38.4 kbit/s","metaDescription":"SIMATIC S7-400 CP 441-1 point-to-point coupling module, 1 channel, max. 38.4 kbit/s, ASCII/3964(R) protocols, mature lifecycle, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC I/O & Expansion Modules"],"specifications":{"Max.":"70 °C","Min.":"0 °C","ASCII":"Yes","Depth":"210 mm","Width":"25 mm","5 V DC":"Yes","Height":"290 mm","RK 512":"No","STEP 7":"Yes; own parameter assignment forms","24 V DC":"Yes","Printer":"Yes","3964 (R)":"Yes","Operation, max.":"95 %; no condensation","Weight, approx.":"800 g; Interface module: 100 g","lifecycle_stage":"mature","Power loss, typ.":"0.3 W","Supported Printers":"HP-Deskjet, HP-Laserjet, IBM-Proprinter, user-defined","Number of interfaces":"1; variable","Transmission rate, max.":"38.4 kbit/s","With Printer Driver, Max.":"38.4 kbit/s","with ASCII protocol, max.":"38.4 kbit/s","with 3964 (R) protocol, max.":"38.4 kbit/s","from backplane bus 5 V DC, max.":"600 mA; Without interface module","Customer-Specific Drivers Reloadable":"No","Memory requirements per interface in memory card of S7-CPU":"1 to 5 KB for parameters; 0 to 55 KB for message texts"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=376534&mlfb=6ES7441-1AA04-0AE0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7441-1AA04-0AE0/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum operating temperature?","answer":"The module is rated for 0 °C to 70 °C ambient operating temperature, with maximum 95% relative humidity, no condensation."},{"question":"What protocols does it support?","answer":"It supports ASCII and 3964(R) protocols at up to 38.4 kbit/s, plus printer drivers for HP-Deskjet, HP-Laserjet, IBM-Proprinter, and user-defined types.
