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

Siemens IM 360 interface module, order number 6ES7 360-3AA01-0AA0, is a central-rack interface for SIMATIC S7-300 systems that expands backplane connectivity by linking the central rack to up to three expansion racks via the C-bus. Installed in the central rack (CC), the IM 360 provides the bus connection required to extend I/O across multiple racks without adding a CPU. It sits in the IM 360/361/365 family of interface modules and is catalogued as 6ES7 360-3AA01-0AA0. The unit is specified for operation in ambient temperatures up to 60°C (temperature class T4). When paired with compatible expansion interface modules and S7-300 CPUs, the IM 360 enables scalable, rack-to-rack I/O distribution and centralized control across multiple racks.
