ET 200M interface for 8 S7-300 modules
The Siemens 6ES7153-1AA01-0XB0 is the ET 200M distributed I/O system interface module for the SIMATIC S7-300 platform, supporting up to 8 S7-300 I/O modules per station.
Compatibility with S7-300 CPUs
This interface module connects directly to the S7-300 backplane bus and is compatible with standard S7-300 CPUs, extending the I/O capacity of a single CPU rack via the ET 200M remote I/O architecture. Each ET 200M station with this module accommodates up to 8 S7-300 signal, function, or communication modules, matching the physical slot count of a typical S7-300 main rack.
The 6ES7153-1AA01-0XB0 is listed at a current lifecycle stage, indicating ongoing production availability through standard Siemens distribution channels.
