Siemens Simatic S7 6ES7315-2EH13-0AB0 Standard CPUs

Description

The 6ES7315-2EH13-0AB0 is a SIMATIC S7-300 CPU 315-2 PN/DP central processing unit featuring 256 KB of work memory and dual communication interfaces. Manufactured by Siemens, this PLC processor is engineered to manage complex control logic, execute automation routines, and handle industrial network communication across medium-to-large-scale manufacturing environments.

The 6ES7315-2EH13-0AB0 is equipped with a first interface supporting MPI/DP at up to 12 Mbit/s and a second Ethernet PROFINET interface for high-speed industrial networking. Operating on a 24 VDC power supply, the unit requires an external Micro Memory Card for user program and data storage. The module measures 12.70 x 10.20 x 12.70 cm and weighs 0.50 kg. As an obsolete lifecycle product with a designated predecessor (6ES7315-2EG10-0AB0) and successor (6ES7315-2EH14-0AB0), it is utilized primarily for legacy system maintenance, hardware replacement, and operational continuity in established S7-300 installations.
