Siemens 7KM9300-0AE01-0AA0 Module

The Siemens 7KM9300-0AE01-0AA0 expansion module is a plug-in Switched Ethernet PROFINET interface for the SENTRON 7KM PAC3200/4200 controllers and related 3VA COM100/800 devices, delivering two RJ45 ports to extend the PAC’s network connectivity. Designed to snap into the PAC backplane, it draws operating power from the host PAC unit and supports PROFINET IO and Modbus TCP, enabling real-time communication and data exchange across industrial networks. Key specifications include insulation up to 500 V AC, a compact form factor of 43 mm wide by 63 mm high by 227 mm deep, and plug-in installation for easy scalability within existing PAC3240/4200 configurations. This model is the 7KM9300-0AE01-0AA0, with Siemens listing noting a successor as 7KM9300-0AE02-0AA0. Intended specifically for the PAC3200/4200 ecosystem, the module provides Switched Ethernet PROFINET connectivity without a separate power supply, making it a straightforward upgrade to expand networked capabilities in SENTRON-based automation architectures.
