Rack PLC CPU unit with 5,120 I/O bits, 60K-step program memory, and 32K words x 3 EM banks.
Discontinued Omron CS1H-series rack PLC CPU unit for the CS1 platform. The CPU65H variant supports up to 5,120 I/O bits, 60K steps of user program memory, 32K words of DM, and 32K words x 3 banks of extended data memory. The platform supports ladder, SFC, ST, and mnemonic programming, with cyclic scan and immediate processing modes. Manufacturer materials also identify built-in peripheral/RS-232C communications support and compatibility with CS-series rack systems.

Controls a high-I/O packaging or assembly line where 5,120 I/O bits and multiple expansion racks are needed to coordinate many sensors, actuators, and station interlocks.
Eliminates I/O capacity bottlenecks in large distributed machine cells.
Handles complex process sequences, recipe tables, and state logic requiring 60K steps of program memory and 32K words x 3 banks of EM for larger control data sets.
Provides enough program and data space for sophisticated automation logic without splitting control across multiple CPUs.
Fits retrofit projects where older plant devices communicate through peripheral and RS-232C ports, allowing reuse of existing serial infrastructure in a CS-series rack system.
Enables modernization without replacing serial field devices or the full control cabinet.
