Siemens, SIPLUS S7-400, 6AG1416-3ES07-7AB0, Work Memory 16 MB, N/A (System Rack Powered), 24 V DC

The Siemens SIPLUS S7-400 CPU 416-3 PN/DP central processing unit (model number 6AG1416-3ES07-7AB0) is a ruggedized controller engineered for large-scale, demanding process automation environments under severe ambient conditions. Drawing power indirectly through the system rack backplane via a 24 V DC base allocation, this specialized variant based on the 6ES7416-3ES07-0AB0 architecture features a protective conformal coating and an extended operating temperature threshold of -25 to +70 C. It provides a massive integrated work memory 16 MB partitioned into equal 8 MB blocks for code and data execution, alongside natively hosted MPI/DP, Industrial Ethernet/PROFINET with an integrated switch, and plug-in IFM communication pathways to smoothly manage localized automation architectures.
