Product details

The Omron CS1G-CPU45H is a CS1G-series CPU with 64K words of program memory, expandable to 80 modules across 7 racks via backplane. 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.

Frequently asked questions

Will the CS1G-CPU45H fit in a panel wired for a CS1G-CPU42H?

Yes. Both are same series, same backplane mount, same communication ports (RS-232C, USB). No rewiring needed – the only difference is the 42H's 30-module limit versus the 45H's 80-module capacity.
