It carries 64K words of program/data memory, RS-232C and USB ports for programming and HMI connection, and mounts on the backplane for power and I/O bus access. ## Expansion Capacity Compared to CS1G-CPU43H The CS1G-CPU44H supports up to 40 modules distributed across 3 racks, whereas the CPU43H (same series, same memory) is limited to 30 modules on 2 racks. If you need more than 30 modules—or prefer the flexibility of a third rack for grouping I/O—the CPU44H is the right pick. Otherwise, both CPUs share identical footprint, backplane, and programming via CX-One. ## Production Status & Sourcing This CPU is listed as an active product by the manufacturer, so there’s no end-of-life pressure or last-time-buy deadline. Standard lead times apply; the part can be specified into a BOM and quoted for scheduled delivery. No special surplus or broker channel needed. ## Panel Fit Notes Mounts on any CS1-series backplane; the CPU occupies one slot and provides the programming port and bus master for expansion racks. Approved for use in CE, cULus, Lloyd, and NK environments.","metaTitle":"CS1G-CPU44H CPU, 64K Words, RS-232C, Active","metaDescription":"CS1G-CPU44H CPU unit from Omron, 64K words memory, RS-232C/USB, supports 40 modules (3 racks).
