Sourcing a discontinued Quantum CPU
The 140CPU43412: Because this CPU is marked EOL hot, it is not available through standard Schneider Electric distribution channels. No official successor part number is recorded for this module.
Fit in a Quantum control system
This module occupies a single slot in a Modicon Quantum rack and communicates over the backplane bus. It is a CPU module, not an I/O expansion module, so it executes the application program and coordinates the I/O scan across the rack. The EOL hot status means a line-down replacement should be sourced before the surplus channel dries up — plan a spare or a migration path to a current Quantum or M340 CPU.
