It draws a maximum of 1.2 A from a 24 V DC supply (permissible range 20.4 V to 28.8 V) and dissipates up to 20 W under full load — that 20 W figure matters for thermal budgeting inside a crowded cabinet; don't tuck it next to a heat-sensitive module without airflow. The IP20 enclosure (67.5 mm deep, 90 mm wide, 132 mm tall) means it's intended for clean, dry control cabinets only — no washdown or dust exposure. The 90 mm width matches the standard SIMATIC S7-300 form factor, so it snaps onto the same DIN rail and aligns with the module row. The 67.5 mm depth leaves clearance for the front connector and cabling — no surprise protrusions. It's a signal amplifier, not a bus node or I/O module — it sits between the PROFIBUS master and the sliding contact segment, boosting the signal to overcome the voltage drop and signal degradation inherent in moving contacts. No addressing or configuration required; it's transparent to the network.","metaTitle":"Siemens 6ES7972-4AA02-0XA0 Power Rail Booster, 20W, IP20","metaDescription":"Siemens SIMATIC DP Power Rail Booster signal amplifier for PROFIBUS DP via sliding contacts, max. 500 Kbit/s.
