Siemens 6ES7416-2XK04-0AB0 Programmable Logic Controller Module

The Siemens 6ES7416-2XK04-0AB0 is a CPU416-2 central processing unit for the SIMATIC S7-400 family, designed as a backplane-compatible module to drive mid‑range automation tasks in an S7‑400 rack. It provides two industrial communication interfaces—MPI/DP at 12 Mbit/s and PROFIBUS DP on the second port—facilitating programming device connections and DP-based I/O networks. The module uses RAM-based memory with 8 MB of integrated work memory, supports isochronous mode on PROFIBUS, and draws approximately 4.5 W of power with the backplane 5 V supply, typically 1 A and up to 1.2 A under peak load. Engineering is performed with STEP 7 V5.2 SP1 HF3 or higher (or STEP 7 V5.4+ with HW Update 261), and the product has been superseded in Siemens’ catalogs by the 6ES7416-2XP07-0AB0, reflecting its status as a spare-part legacy model.
