Omron CS1G-CPU43H CS1 Series CPU Processor Unit

Description

Engineered for high-reliability industrial automation, the CS1G-CPU43H serves as a core central processing unit within the Sysmac CS1 series programmable logic controller (PLC) family. This CPU processor module offers a balanced allocation of program memory and data register capacity, optimized for mid-to-high-scale factory automation, process control, and machine coordination. Utilizing a dedicated processor engine, it delivers high-speed sequence execution and handles arithmetic operations efficiently, minimizing overall system scan times.

The integrated architecture allows for seamless expansion, supporting direct connections to local I/O modules as well as multi-rack expansion configurations. Communication capabilities are integrated directly into the module faceplate, providing native channels for programming interfaces, operator panels, and legacy host link connections without requiring dedicated communication cards. It is designed to mount securely onto standard CS1-series backplanes, interfacing with standard power supplies and specialized functional units.

Installation Guidelines

• Always switch off the main system power supply before inserting or removing the CPU unit from the backplane to prevent structural damage or electrical shock.
• Ensure that the CPU unit is locked firmly into position using the mounting hooks on the backplane.
• Provide adequate ventilation clearance around the CPU unit as defined in the Omron CS1 hardware manuals to prevent localized thermal buildup.
• Connect the system ground terminal on the associated power supply unit directly to a low-impedance ground point using heavy-gauge copper wiring.

Compliance and Certifications

• CE Mark (EMC Directive)
• cULus Listed
• NK Marine Standard (where designated)
