Siemens 6ES7 315-2AH14-0AB0 S7-300 CPU Module

Siemens 6ES7315-2AH14-0AB0 is a SIMATIC S7-300 CPU 315-2DP central processing unit designed for scalable PLC control in manufacturing environments. It delivers MPI connectivity for programming and diagnostics and an additional DP interface (master or device) to integrate with DP-enabled I/O and networks, enabling mixed MPI/DP topologies within a single CPU. The module includes an internal 24 V DC power supply and offers 256 KB of working memory for program and data storage, supporting mid-size control tasks. A Micro Memory Card is required for program storage, consistent with the S7-300 architecture. Power is supplied from 24 V DC and typically draws about 750 mA; the unit carries a temperature class T4 for operation in standard industrial environments. This part is sold as a Siemens Industry Mall spare part, providing a direct replacement option for S7-300 installations that previously used the 315-2DP CPU and ensuring compatibility with MPI networks and DP devices in the S7-300 family.
