Siemens 6ES7 360-3AA01-0AA0 Programmable Logic Controller Module

Siemens 6ES7 360-3AA01-0AA0 is the IM360 interface module that serves as the central rack interface in a SIMATIC S7-300 multi‑rack configuration, installed in Rack 0 to connect the backplane bus to expansion racks. In a two‑to‑four rack setup, IM360 (Rack 0) works with IM361 (Rack 1–3) to span up to three expansion racks, enabling distribution of I/O and control across multiple racks. Connecting cables for the interface chain include 6ES7 368-3BB00-0AA0 (1 m), 6ES7 368-3BC50-0AA0 (2.5 m), 6ES7 368-3BF00-0AA0 (5 m), and 6ES7 368-3CB00-0AA02-10 (10 m), which link IM360 to IM361 and other racks as part of the backplane interconnect. This configuration and part numbers are referenced in Siemens’ M7-300 IM360/IM361 documentation and related Industry Mall product listings.
