It is designed specifically to couple with a Festo CPV-14 valve terminal, so the BOM line is locked to that mating half — no generic pneumatic manifold substitution without changing the terminal block. ## Pressure and flow envelope The permissible working pressure range is 3 bar minimum to 8 bar maximum, with a rated flow of 800 l/min on compressed air filtered to 40 µm — oiled (VG 32) or unoiled/vacuum service is acceptable. Each valve draws up to 32 mA; the total load from the 2L+ supply, including valves, is 520 mA max, with an additional 45 mA drawn from the 5 V DC backplane bus. ## Isolation and power budget Channel-to-channel isolation is provided in groups of 16, and an optocoupler isolates the channels from the backplane bus — this keeps field-side transients off the DP network. Typical power loss is 9 W, which factors into the ET 200X enclosure thermal budget — no active cooling needed in a standard IP20 cabinet, but the heat adds up if multiple modules are ganged.","metaTitle":"Siemens 6ES7148-1EH11-0XA0 Pneumatic Interface, 16 DO","metaDescription":"SIMATIC DP pneumatic interface module for ET 200X, 16 outputs for valve control, 800 l/min flow, 3-8 bar working pressure, compatible with Festo CPV-14.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC I/O & Expansion Modules"],"specifications":{"Depth":"53 mm","Width":"147 mm; Width module 120 mm","title":"6ES7148-1EH11-0XA0","Height":"152 mm","Medium":"Compressed air filtered (40 µm), oiled (oil: VG 32), not oiled/vacuum","description":"***Spare part*** SIMATIC DP, Pneumatic interface EM 148-P for ET 200X 16 DO pneumatics for coupling with Festo valve terminal CPV-14;","Per Valve, Max.":"32 mA","Rated flow rate":"800 l/min","lifecycle_stage":"current","Power loss, typ.":"9 W","Connectable Valves":"CPV 14 standard spectrum","Between The Channels":"Yes","from load voltage 2L+, max.":"520 mA; Including valves","from backplane bus 5 V DC, max.":"45 mA","Between The Channels, In Groups Of":"16","Number of connectable valves, max.":"8; 8 valve disks (up to 16 valve functions)","Permissible Working Pressure, Max.":"8 bar","Permissible Working Pressure, Min.":"3 bar","Number of outputs for valve control":"16","Between The Channels And Backplane Bus":"Yes; Optocoupler"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$281.75","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/eaa2d09cb181f4f534f179bc0da588d0.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=181908&mlfb=6ES7148-1EH11-0XA0"},"ai":{"faq":[{"question":"Is 6ES7148-1EH11-0XA0 compatible with Festo CPV-14?","answer":"Yes — the module is specifically designed for coupling with a Festo CPV-14 valve terminal, as stated in the product description."},{"question":"What is the working pressure range for 6ES7148-1EH11-0XA0?","answer":"The permissible working pressure range is 3 bar minimum to 8 bar maximum, with a rated flow of 800 l/min."},{"question":"How many valves can 6ES7148-1EH11-0XA0 connect?","answer":"It connects up to 8 valve disks, which provides up to 16 valve functions, controlled through 16 digital outputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7148-1EH11-0XA0","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/6ES7148-1EH11-0XA0 when reusing this data.
