Siemens 6ES7416-2XN05-0AB0 S7-400 PLC CPU Module

Siemens 6ES7416-2XN05-0AB0 is a SIMATIC S7-400 CPU 416-2 central processing unit designed for industrial automation tasks, offering 5.6 MB of working memory (2.8 MB code, 2.8 MB data) and two built-in fieldbus interfaces: an MPI/DP at 12 Mbit/s and a second PROFIBUS DP interface, enabling connections to both programming tools and distributed devices. This CPU is part of the S7-400 family and is intended for operation on a 24 V DC backplane, with backplane current up to 1.1 A. Each DP interface can draw up to 150 mA from the 5 V supply. Common applications include factory and process automation where reliable dual-communication paths and a compact memory footprint are required for executing control logic and handling I/O data in mid-scale systems.
