Product details

The Omron CS1H-CPU65H is a CS1H-series PLC CPU with 128K words of program memory, expandable to 80 modules across 7 racks, communicating via RS-232C and USB. It mounts on a backplane (same rack as I/O, special function, and communications modules) and is programmed using the CX-One software suite.

Integration notes

Communication ports are RS-232C and USB. RS-232C covers programming and connection to legacy HMIs or serial devices; USB handles fast program downloads. Expand via the backplane to up to 80 modules (7 racks) without extra interfacing.

Frequently asked questions

What approvals does the CS1H-CPU65H carry?

It carries CE, cULus, Lloyd, and NK approvals.

Can I drop this CPU into a panel that was specified around the CS1H-CPU63H?

Yes. The CS1H-CPU63H and CS1H-CPU65H share the same form factor, backplane, power supply, and I/O rack structure. The only change is memory: 128K words instead of 64K.
