CPU capacity for a redundant rack
The CS1D-CPU67SA is a single CPU unit for the Omron CS1D redundant PLC system, offering 250K program steps and 416K data memory — enough headroom for a medium-to-large process skid with recipe management and alarm history.
No official successor order code has been issued; the CS1D-CPU67SA remains the current CPU for the CS1D rack.
Rack compatibility
This CPU mounts directly into the CS1D backplane — no adapter or slot restriction. The single-CPU variant runs the same I/O and communications modules as the dual-CPU configuration, just without the redundant processor pair.
