The Siemens 6AG1654-5CN00-7XF0 is an active-production SIPLUS PCS 7 CPU 410-5H bundle, specified for process automation on S7-400 and S7-400H systems with up to 1000 process objects. It is the conformal-coated, extended-temperature variant of the 6ES7654-5CN00-0XF0, rated for -25...+70 °C ambient — built for the heat and condensation you find in process plants.
Lifecycle & Sourcing Reality
Export control classification AL:N / ECCN 9N9999 indicates no unusual restrictions for industrial automation shipments.
Integration Note
This CPU mounts in a standard S7-400 rack and uses the same backplane as the standard 410-5H. The conformal coating protects against humidity, dust, and chemical vapors — a common need in chemical, oil & gas, and mining process skids. The extended temperature range covers plant-floor conditions where standard CPUs might fail.
