It sits inline on the PROFIBUS cable to perform online cable diagnosis — detecting breaks, shorts, or degradation — while acting as a standard DP slave up to 12 Mbit/s. Runs on 24 V DC nominal, with a permissible range of 20.4 V to 28.8 V DC. The terminal module handles the supply connection; the PROFIBUS side uses FastConnect insulation displacement, rated for 10 clamping cycles. Dimensions are 80 mm wide, 125 mm high, 67.5 mm deep. Approx. 300 g. Snap it onto a standard DIN rail inside the enclosure; leave clearance for the FastConnect cable entry and the terminal module on the supply side. Transmission rate is autobauding from 9.6 kbit/s to 12 Mbit/s — no DIP switches to set. The diagnosis function works across the full range, so it doesn't impose a speed limit on the segment.","metaTitle":"Siemens 6ES7972-0AB00-0XA0 Diagnosis Repeater, 12 Mbit/s PRO","metaDescription":"Siemens SIMATIC S7 diagnosis repeater for PROFIBUS-DP online cable diagnosis. 24 V DC, 12 Mbit/s, IP20, FastConnect.
