Siemens AG 6ES7 360-3AA01-0AA0 Interface Module

The Siemens 6ES7360-3AA01-0AA0 IM360 interface module is the central link in SIMATIC S7-300 systems, connecting the main rack to up to three expansion racks. In central controller configurations it provides the backplane bus connection to remote racks via the K-Bus, with related IM 360/IM361/IM365 modules forming a multi-rack S7-300 architecture. Listed in Siemens catalogs as the IM 360 central rack interface module with order number 6ES7360-3AA01-0AA0, it is used to extend I/O and communications within a single S7-300 control network. This enables scalable, modular automation layouts by letting a single CPU coordinate multiple I/O racks in a compact, centralized configuration.
