It carries 16 process terminals for the I/O module plus 2x5 add-on terminals (CC74 compatible) for auxiliary connections like shields or external power. The push-in terminals accept 0.14 mm² to 2.5 mm² (AWG 26–14) solid or ferruled wire, so no screwdriver needed for termination — just strip to 8 mm and press in. It also integrates a temperature sensor for module-level thermal monitoring. ## Fit and mounting constraints Depth is 35 mm — that's the space from the rail to the front of the terminal block, so account for it in your enclosure depth planning. It bridges the potential group from the left and does not create a new potential group, meaning it continues the same 24 V DC supply rail from the adjacent left-side BaseUnit. The and bus bars carry up to 10 A; the process terminals are rated at 2 A max. For the 24 V DC supply lines, Siemens calls for an external miniature circuit breaker rated 24 V DC / 10 A with type B or C tripping characteristic. ## Environmental limits and derating Horizontal installation permits ambient temperatures from -30 °C to 60 °C; vertical installation derates the max to 50 °C. Installation altitude goes up to 5 000 m, but above 2 000 m you need to follow the manual's restrictions for reduced air density and cooling. The isolation is type-tested at 707 V DC — that's the dielectric strength between the bus and field circuits, not an operating voltage.","metaTitle":"Siemens 6ES7193-6BP40-0BA1 ET 200SP BaseUnit, BU15-P16+A0+12","metaDescription":"Siemens 6ES7193-6BP40-0BA1 SIMATIC ET 200SP BaseUnit, Type A1, 15 mm wide, push-in terminals, 16 process terminals, 2x5 add-on terminals, temperature sensor, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLC I/O & Expansion Modules"],"specifications":{"Depth":"35 mm","Width":"15 mm","Height":"141 mm","Terminal type":"Push-in terminal","Number of slots":"1; Type A1","Weight, approx.":"50 g","lifecycle_stage":"current","Rated value (DC)":"24 V","for AUX terminals":"does not exist","Temperature sensor":"Yes","New potential group":"No","Additional terminals":"Yes","For Add-On Terminals":"CC74","HW functional status":"FS10 and higher","For Process Terminals":"CC00 to CC09","Isolation tested with":"707 V DC (type test)","For P1 and P2 bus, max.":"10 A","Number of add-on terminals":"2x5","For process terminals, max.":"2 A","Vertical Installation, Max.":"50 °C","Vertical Installation, Min.":"-30 °C","Conductor cross-section, max.":"2.5 mm²; AWG 14","Conductor cross-section, min.":"0.14 mm²; AWG 26","Horizontal Installation, Max.":"60 °C","Horizontal Installation, Min.":"-30 °C","Number of terminals to AUX bus":"0","System-Integrated Shield Connection":"Yes; Optional","Potential group continued from the left":"Yes","Number of process terminals to I/O module":"16","External Protection For Power Supply Lines":"Yes; 24 V DC/10 A miniature circuit breaker with type B or C tripping characteristic","Installation altitude above sea level, max.":"5 000 m; Restrictions for installation altitudes > 2 000 m, see manual","Number of terminals with connection to P1 and P2 bus":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.88","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ec01ed53bba8e776e59e378e4f3d4804.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=495560&mlfb=6ES7193-6BP40-0BA1","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7193-6BP40-0BA1/alternatives.json"},"ai":{"faq":[{"question":"What is the width and depth of this BaseUnit?","answer":"Width is 15 mm, depth is 35 mm, height is 141 mm.
