64K Word Memory, 80-Module Capacity
The Omron CS1H-CPU63H is a rack-mount PLC CPU from the CS1H series, with 64K Words of program memory — enough headroom for mid-to-large machine control sequences without forcing a memory expansion module. It supports up to 80 I/O modules across a maximum of 7 racks, so a single CPU can handle a distributed chassis layout with local and remote racks tied through the backplane.
Communications and Approvals
Built-in RS-232C and USB ports cover the common commissioning and HMI links — no separate serial card needed for programming or SCADA connection. Approved to CE, cULus, Lloyd's Register, and NK (Nippon Kaiji Kyokai), so it meets the certification requirements for European, North American, and marine-class installations.
For a BOM that depends on this CPU, the procurement decision is time-sensitive: source against an RFQ now to lock in available inventory before the supply channel tightens.
