Siemens 6AG1512-1DK00-2AB0 DC/DC/DC CPU features DCP, IRT, MRP redundancy, measures 100×117×75 mm, and has an I²t rating of 0.14 A²·s that bounds short-circuit energy on outputs.
Key ratings and their meaning
MRP redundancy manager or client handles ring topologies with up to 50 devices; IRT enables deterministic cycle times for drives and motion. DCP (Yes) means the CPU is powered from a 24 V DC supply — no AC option. The integrated PID-Temp and blocks handle temperature and valve control directly in the logic. I²t of 0.14 A²·s is a withstand rating for the output semiconductors — treat it as a short-circuit limitation, not a continuous load. Watch your fuse clearing time and energy let-through to stay under this.
