Product details

What the CS1H-CPU67H carries: 448K words and 80-module expansion

The Omron CS1H-CPU67H is a Control Logic CPU from the CS1H series, built for mid-to-large scale automation. Program memory sits at 448K Words, enough for complex sequencing, motion, or process loops. Expandability tops out at 80 modules spread across up to 7 racks, so the I/O count scales with the machine. Communication ports are RS-232C and USB — the RS-232C covers legacy HMIs or drives; USB handles programming via CX-One. The CPU mounts on a backplane, not DIN rail, so plan the rack layout accordingly.

Backplane mounting and rack sizing

The CPU installs into a CS1-series backplane and supports up to 7 racks with 80 modules. Program memory is 448K Words.

Frequently asked questions

What is the memory size of this CPU?

The program memory is 448K Words.

How many modules and racks can this CPU support?

It supports up to 80 modules across a maximum of 7 racks.

What certifications does this CPU carry?

It is approved by CE, cULus, Lloyd, and NK.

Can the CS1H-CPU67H be used in place of a CP1L-series CPU?

No. The CS1H uses backplane mounting and supports up to 80 modules, while CP1L CPUs are chassis/DIN-rail mount and limited to 1 or 3 modules. They are not physically or electrically interchangeable.
