Omron CJ1M-CPU22 SYSMAC CJ-series CJ1M CPU Unit

Description

The Omron CJ1M-CPU22 is a compact central processing unit belonging to the SYSMAC CJ-series, configured with built-in digital I/O functions. It is designed to manage small-to-medium industrial automation applications requiring rapid logic processing and compact control integration. Operating as the system controller, it delivers an execution speed of 0.1 µs for basic LD instructions and handles a program capacity of 10K steps along with 32K words of data memory. The hardware integrates local discrete inputs and outputs, independent high-speed counter inputs, and dedicated pulse outputs for position handling without additional modules. This CPU unit supports up to 10 local Units on a single rack system, ensuring direct compatibility with standard Omron SYSMAC CJ-series I/O modules, power supplies, and industrial communication interfaces.

Features

• Integrated onboard digital I/O layout comprising 10 discrete inputs and 6 discrete outputs.
• Built-in motion support with 2 high-speed counter inputs and 2 pulse outputs.
• Fast instruction processing with an LD execution execution speed of 0.1 µs.
• Direct local scalability supporting up to 10 mountable units without expansion racks.
• Solid-state memory allocation with 10K steps program capacity and 32K words data memory.
• High efficiency internal configuration drawing a low 0.64 A current consumption.

Applications

• High-speed packaging machinery and automated wrapping stations.
• Small-scale multi-axis positioning tables and component pick-and-place systems.
• Conveyor sortation systems and localized material handling automation.

Installation Guidelines

• Rack Mounting: Slide the CPU unit firmly into position onto the dedicated CJ-series backplane or adjoining power supply unit. Engage the top and bottom locking levers to verify a stable connection.
• DIN Rail Installation: Mount the assembled assembly onto standard 35mm DIN rail tracks inside an industrial enclosure, securing both ends with end plates to mitigate shifting from system vibration.
• Airflow and Ventilation: Ensure a minimum clearance space around the unit inside the electrical enclosure to permit regular convection cooling. Avoid placing high-heat producing components directly below the processor.
• Cable Separation: Route sensitive low-voltage built-in I/O and communication cables through pathways separate from noisy high-voltage AC mains lines or heavy motor drive cables to prevent electromagnetic interference (EMI).
• System Grounding: Utilize the grounding terminal located on the adjoining system power supply module, running a low-impedance connection directly to the main control panel earth terminal.
