Official Part Number CS1H-CPU64H
GTIN Standard NA

Technical Overview

CS1H-CPU64H is an Omron CS1-series rack-mounted PLC CPU unit. Official Omron and distributor sources identify it as a discontinued CS1H controller with 5,120 I/O bits, 30K-step user program capacity, 64K words of data memory, and onboard peripheral plus RS-232C communications. It is positioned for large modular automation systems with up to 7 expansion racks / 80 modules, and is part of Omron's CS1 family for integrated machine and process control.

Key Features

  • 5,120 I/O bits for large distributed machine control

Industrial Applications

1. High-channel-count packaging line control

A rack PLC controlling many synchronized sensors, actuators, and sequence steps across a packaging machine or line.

Problem Solved

Provides enough I/O and memory for large multi-station sequencing without splitting logic across multiple controllers.

2. Process skid coordination and interlocking

A central controller for process skids that need coordinated pump, valve, alarm, and permissive logic.

Problem Solved

The 64K-word memory and serial communications support complex interlocks and operator integration in a compact control architecture.
