Siemens, SIPLUS S7-400, 6AG1416-3XS07-7AB0, Work Memory 16 MB, N/A (System Rack Powered), 24 V DC

The Siemens SIPLUS S7-400 CPU 416-3 central processing unit (model number 6AG1416-3XS07-7AB0) is a ruggedized controller engineered for large-scale, demanding process automation environments. Drawing power indirectly through the system rack backplane via a 24 V DC base allocation, this specialized variant based on the 6ES7416-3XS07-0AB0 architecture features an integrated conformal coating and an extended operating temperature range 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, PROFIBUS DP, and plug-in IFM communication pathways to smoothly manage localized automation architectures.
