It ships with RS-232C and USB ports, runs under CX-One software, and carries CE, cULus, Lloyd, and NK approvals. Built for the pit – this CPU shrugs off the vibration you get in a crusher panel and is rated for combustible dust atmospheres. ## Swap from CS1G-CPU42H? If your BOM carried the CS1G-CPU42H, the CS1G-CPU45H drops into the same backplane without rewiring. Same series, same mounting, same comms. The difference: the 42H maxes out at 30 modules (2 racks), while the 45H handles 80 modules (7 racks). That extra rack headroom matters if you're populating a large I/O bank.","metaTitle":"Omron CS1G-CPU45H PLC CPU, 64K Words, 80 Modules","metaDescription":"Active Omron CS1G-CPU45H CPU with 64K word memory, 80-module expandability, RS-232C/USB.
