CJ1 Series Programmable Logic Controllers (PLCs) are high-performance modular automation platforms designed for complex industrial control tasks. These controllers feature a compact CPU unit with integrated I/O, supporting up to 40 I/O points in basic configurations, with expansion capabilities via CJ-series I/O units, Special I/O units, and CPU Bus units. The CJ1 series offers multiple CPU models with varying program capacities (from 10K to 250K steps) and processing speeds (as fast as 0.02 μs per basic instruction). Key technical specifications include support for multiple programming languages (ladder diagram, structured text, instruction list, and function block diagrams), built-in Ethernet/IP, DeviceNet, or serial communication ports depending on the CPU model, and a maximum of 80 units per rack. The series also features a real-time clock, battery-backed RAM, and flash memory for program storage. These controllers are engineered for high-speed processing and deterministic control in applications requiring precise timing and synchronization.
CJ1 PLCs are deployed across a wide range of industrial sectors including automotive manufacturing, packaging machinery, material handling systems, water treatment facilities, and semiconductor production lines. They are typically installed in main control panels, distributed control cabinets, and automation islands within factory floors. Common applications include machine control, process automation, motion control coordination, and data acquisition systems. The modular architecture allows for flexible configuration to meet specific application requirements, from simple relay replacement to complex multi-axis motion control.
The CJ1 series encompasses several subcategories including CJ1G-CPU (high-performance CPUs with built-in Ethernet), CJ1H-CPU (high-speed CPUs for advanced motion control), and CJ1M-CPU (compact CPUs for basic control). Key article codes follow the pattern CJ1W-AD041-V1 (analog input unit), CJ1W-DA041 (analog output unit), CJ1W-ID211 (DC input unit), CJ1W-OC201 (relay output unit), and CJ1W-NC113 (position control unit). The CPU unit codes are structured as CJ1G-CPU44P, CJ1H-CPU66H, and CJ1M-CPU13, where the suffix indicates performance level and features. Additional specialized units include CJ1W-SCU31-V1 (serial communication unit) and CJ1W-CLK23 (Controller Link unit).
Electric Automation Network provides comprehensive support for CJ1 series PLCs including real-time pricing, technical documentation with wiring diagrams and programming manuals, and express worldwide shipping. Our engineering team offers specialized technical assistance for system configuration, troubleshooting, and integration with existing automation architectures. We maintain a large inventory of CPU units, I/O modules, and communication units to ensure rapid delivery for both planned upgrades and emergency replacements.
