Maximum transmission rate is 19.2 kbit/s across all protocols, with ASCII and 3964(R) supporting up to 76.8 kbit/s in half-duplex mode. The 20 mA TTY interface supports cable runs up to 1 000 m, making it suitable for point-to-point links across a plant floor where RS-232 would drop out. ## Panel fit and power budget The module occupies a single S7-300 slot at 40 mm wide, 125 mm tall, 120 mm deep. It draws 70 mA from the 5 V backplane bus and up to 200 mA from the 24 V DC supply via three screw terminals (L+, M, GND). Maximum power dissipation is 4.8 W — account for this in the enclosure thermal budget, especially in a densely populated rack.","metaTitle":"Siemens 6ES7341-1BH01-0AE0 CP 341, 20 mA TTY, EOL","metaDescription":"Siemens CP 341 communications processor with isolated 20 mA TTY interface. 1 024 byte ASCII buffer, 19.2 kbit/s.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"ASCII":"1 024 byte","Depth":"120 mm","Width":"40 mm","Height":"125 mm","RK 512":"1 024 byte","24 V DC":"Yes","3964 (R)":"1 024 byte","Connector type":"9-pin sub D connector","Weight, approx.":"300 g","lifecycle_stage":"eol_hot","Power loss, max.":"4.8 W","Cable length, max.":"1 000 m","Interfaces/bus type":"20 mA (TTY)","Number of interfaces":"1; Isolated","FB length in RAM, max.":"5 500 byte; Data communication, sending and receiving","Transmission rate, max.":"19.2 kbit/s","Transmission rate, min.":"0.3 kbit/s","with ASCII protocol, max.":"76.8 kbit/s; 0.3; 0.6; 1.2; 2.4; 4.8; 9.6; 19.2; 38.4; 57.6 and 76.8 kbit/s (76.8 kbit/s only achievable with half duplex)","with RK 512 protocol, max.":"76.8 kbit/s","from supply voltage L+, max.":"200 mA","with 3964 (R) protocol, max.":"76.8 kbit/s","from backplane bus 5 V DC, max.":"70 mA","Customer-Specific Drivers Reloadable":"Yes","Design of electrical connection for supply voltage":"3 screw-type terminals: L+, M, GND"}},"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=195629&mlfb=6ES7341-1BH01-0AE0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7341-1BH01-0AE0/alternatives.json"},"ai":{"faq":[{"question":"Does the 6ES7341-1BH01-0AE0 require a configuration package?","answer":"Yes, it ships with a configuration package on CD as noted in the spare part description."},{"question":"Can the 6ES7341-1BH01-0AE0 be used with a 20 mA TTY interface?","answer":"Yes, the module has one isolated 20 mA (TTY) interface via a 9-pin sub-D connector, supporting cable runs up to 1 000 m."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7341-1BH01-0AE0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6ES7341-1BH01-0AE0 when reusing this data.
