Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 6ES7972-0AB01-0XA0 is a Siemens SIMATIC S7 diagnostic repeater for PROFIBUS DP networks, designed for online diagnostics of the PROFIBUS cable. It operates as a DP standard slave at transmission rates from 9.6 kbit/s up to 12 Mbit/s, with FastConnect connection method and IP20 protection for in-cabinet mounting. This unit draws 4.0 W from a 24 V DC supply, mounts on DIN-rail, and uses screw terminals. It measures 80 x 125 x 67.5 mm (width x height x depth) and weighs 300 g. The diagnostic repeater sits inline on a PROFIBUS DP segment, regenerating the signal and providing real-time cable diagnostics. It detects and reports physical-layer faults such as short circuits, wire breaks, and missing terminations, which helps a field service tech isolate a failing segment without disconnecting the bus. Transmission rate is configurable from 9.6 kbit/s to 12 Mbit/s, matching the segment's baud rate. The FastConnect method uses standard PROFIBUS connectors with quick-connect terminals, reducing wiring time during commissioning. ## Applications This diagnostic repeater is used on PROFIBUS DP networks in manufacturing lines, process plants, and material-handling systems where cable faults cause intermittent communication drops. It allows maintenance teams to locate and repair cable faults without a bus analyzer, reducing downtime on critical segments.","metaTitle":"Siemens 6ES7972-0AB01-0XA0 SIMATIC PROFIBUS DP Diagnostic Repeater","metaDescription":"Siemens SIMATIC S7 diagnostic repeater for PROFIBUS DP, 6ES7972-0AB01-0XA0, 12 Mbit/s, IP20, FastConnect, phase-out since 2024-10-01.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["PLC Accessories"],"specifications":{"Max.":"70 °C","Min.":"-40 °C","Depth":"67.5 mm","Width":"80 mm","Height":"125 mm","Operation, max.":"95 %; at 25 °C","Weight, approx.":"300 g","lifecycle_stage":"mature","Power loss, typ.":"4 W","Rated value (DC)":"24 V","IP degree of protection":"IP20","Transmission rate, max.":"12 Mbit/s; 9.6 kbit/s to 12 Mbit/s","permissible range, lower limit (DC)":"20.4 V","permissible range, upper limit (DC)":"28.8 V","Design of electrical connection for supply voltage":"Terminal module","Design of electrical connection for PROFIBUS cables":"FastConnect insulation displacement, 10 clamping cycles possible"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$304.80","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b23427fd3dedb12f96273e23b2ba0d9f.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=134653&mlfb=6ES7972-0AB01-0XA0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7972-0AB01-0XA0","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/6ES7972-0AB01-0XA0 when reusing this data.
