OMRON CJ Series PLC Programmable Logic Control Controllers I/O Module -CJ2H/CJ2M Series Controller

Description:

The OMRON CJ2H and CJ2M Series represent the pinnacle of modular, high-performance programmable logic controllers, engineered to meet the diverse needs of modern industrial automation . Evolved from the field-proven CJ1 platform, these controllers offer a seamless upgrade path with consistent architecture across the entire CJ2 family, making it easy to scale applications from simple machine control to complex, high-speed production lines . The CJ2H series delivers flagship performance for advanced machinery, such as high-speed sorting and image inspection, with ultra-fast processing and large memory capacities that ensure precision and efficiency . The CJ2M series provides a versatile and cost-effective solution for packaging and general automation, offering flexible connectivity options and dedicated function block memory for structured, object-oriented programming . With built-in USB ports for plug-and-play access, optional EtherNet/IP for real-time data sharing, and a vast library of compatible I/O units, the CJ2 series simplifies system design, reduces time-to-market, and maximizes machine uptime . Whether you need synchronized multi-axis control or high-speed counting, the CJ2 platform delivers the reliability and performance that define OMRRON automation .

The Omron CJ2H and CJ2M Series are advanced, modular programmable logic controllers (PLCs) designed for high-performance machine automation. They succeed the popular CJ1 series, offering faster processing speeds, increased memory capacity, and enhanced built-in communication capabilities.

While they share a common architecture, they are positioned for different application needs:

1. CJ2H Series (High-Performance Model)

The CJ2H is designed for complex and high-speed applications requiring maximum processing power and memory.

• CPU Types: Available in standard and power-CPU versions.

• Program Capacity: Ranges from 50K to 400K steps, capable of handling large-scale programs.

• Data Memory: 160K to 832K words.

• Processing Speed: Very fast at 0.016 µs for basic instructions.

• Built-in I/O: No built-in I/O on the CPU.

• Networking: Standard built-in EtherNet/IP port and USB port for high-speed data exchange with IT systems and HMIs.

• Motion Control: Supports complex multi-axis synchronization via specialized Position Control Units (up to 20 axes).

• Best For: High-end machinery, high-speed packaging, electronic component assembly, and systems requiring large data processing or complex motion.

2. CJ2M Series (Versatile/Scalable Model)

The CJ2M is designed for cost-effective, general machine control with high flexibility in connectivity.

• CPU Types: A wide variety of CPU units with different built-in functionalities.

• Program Capacity: Ranges from 5K to 60K steps.

• Data Memory: 64K to 160K words.

• Processing Speed: 0.04 µs for basic instructions.

• Built-in I/O: Some CPU models feature built-in I/O, including high-speed counters (100kHz, 4 axes) and interrupt inputs.

• Simple Positioning: Supports up to 4 axes of simple positioning via optional pulse output modules (up to 1MHz).

• Networking: Standard USB port. Optional built-in EtherNet/IP port available. Serial communication can be added via optional serial boards (RS-232C/422/485).

• Best For: General automation, packaging machines, material handling, and applications requiring built-in I/O or simple motion control.

Key Features Shared by Both Series

• Function Block (FB) Support: Allows for reusability of code, reducing programming time and standardizing machine operations.

• SD Memory Card Slot: Standard on both models for easy program transfer, data logging, and device maintenance (simple backup function).

• Rich Lineup of Units: Fully compatible with the extensive CJ Series Special I/O Units and Basic I/O Units (Analog, Temperature Control, Communication, etc.).

• Unified Architecture: Programs and settings are compatible across the series, allowing for easy scalability (upgrading from CJ2M to CJ2H without major software overhauls).

Selection Guide

• Choose the CJ2H if you need maximum speed, large program capacity, complex motion control, or high-level Ethernet connectivity.

• Choose the CJ2M if you need a cost-effective solution with flexible connectivity (serial/Ethernet options) and the option for built-in I/O for general machine control.
