Siemens 6ES7312-1AD10-0AB0 CPU Module for SIMATIC S7-300

Siemens 6ES7312-1AD10-0AB0 is a CPU module for the SIMATIC S7-300 PLC family (CPU 312) with an integrated MPI interface and a built‑in 24 V DC power supply. It provides 16 KB of working memory and requires a micro memory card (minimum 2 MB) for program and data storage. Firmware support begins at version 2.0.0 or newer for this order number. Designed to be installed in an S7-300 rack, this CPU module enables MPI communication with other controllers and devices, making it suitable for compact automation tasks where CPU 312 capabilities are required. Its combination of an integrated power supply, onboard RAM, and MPI connectivity supports streamlined setups in legacy S7-300 installations and simplifies wiring by reducing external power components.
