It runs on a 24V DC integrated power supply and carries 6 KB of working memory. There is no official Siemens successor order code on record for this specific variant; any migration requires evaluating the current S7-1200 or S7-1500 family for a functional equivalent, which will involve a different form factor and software porting. The 10 DI / 6 DO count defines the onboard I/O — no expansion module needed for small machine cells or standalone stations. The integrated counter and frequency measurement handle encoder or pulse-train inputs directly, saving a separate counter module slot. The 6 KB working memory limits program size to small logic sequences; per the datasheet, this is a compact controller for simple automation tasks, not a multi-axis or data-heavy application. The 24V DC supply is standard for industrial control panels. The 20-pin front connector matches the S7-300 backplane bus; the CPU snaps onto the DIN rail in the same rack as I/O modules. No separate power module is required for the CPU itself.","metaTitle":"Siemens 6ES7312-5AC02-0AB0 CPU 312 IFM, EOL Hot","metaDescription":"Siemens SIMATIC S7-300 CPU 312 IFM with 10 DI/6 DO, 24V DC, 6 KB working memory.
