About the Siemens 6ES7307-1KA02-0AA0
The Siemens 6ES7307-1KA02-0AA0 is the 10 A member of the PS307 range; its siblings are the 2 A 6ES7307-1BA01-0AA0 and the 5 A 6ES7307-1EA01-0AA0. Siemens's data sheet gives a 120/230 V AC input with automatic range selection, a controlled, isolated 24 V DC output at 10 A (240 W), 20 ms of mains buffering and an 80 × 125 × 120 mm housing that mounts on the S7 rail. SiePortal shows its product cancellation on 1 October 2026, a year after most of the S7-300 range.
What is the 6ES7307-1KA02-0AA0 used for?
It supplies 24 V DC to an S7-300 CPU, its I/O load circuits and field devices where a 2 A or 5 A supply is not enough.
Lifecycle and successor
Discontinued.
