Siemens 6ES7153-1AA03-0XB0 is the IM 153-1 DP interface module for ET 200M, designed to connect a PROFIBUS DP network to remote I/O blocks in an S7-300-based system. It supports up to eight S7-300 modules on a single DP slave interface and operates on 24 V DC, enabling scalable expansion within Siemens automation architectures. The interface provides a PROFIBUS DP communications link (RS-485 physical layer) for ET 200M, facilitating reliable distributed I/O connectivity in industrial environments.
