OEMAX NX-BASE08 PLC Base Unit

Product Description

The OEMAX NX-BASE08 is a fundamental mounting and communication base unit designed for Omron’s NX Series machine automation controllers. This unit serves as the physical and electrical backbone, providing the essential structure, power distribution, and high-speed internal data bus for connecting a CPU module and various I/O modules. The OEMAX NX-BASE08 forms the foundational “rack” of a compact, modular PLC system, allowing for the creation of a tailored control solution by snapping different functional modules onto its front connector. Its robust design ensures secure connections and stable operation in industrial environments. For complete technical documentation, compatibility lists, and configuration details, please visit the official product information page: OEMAX NX-BASE08. Integrating the NX-BASE08 base unit is the first critical step in building a high-performance NX Series control system, enabling the seamless combination of processing power, I/O points, and specialty functions. The reliability and precision of this base unit are paramount, as it is the conduit for all power and high-speed data exchange between every module in the local rack, including the CPU, digital/analog I/O, and motion control units.

Product Parameters

• Compatible Modules: Designed to host the NX Series CPU Unit, NX Unit power supply, and a wide array of NX I/O Units (Digital, Analog, Temperature, Communication, etc.).

Advantages and Features

• Modular and Scalable Design: The 8-slot configuration of the OEMAX NX-BASE08 offers excellent flexibility, allowing engineers to mix and match exactly the I/O and special function modules required for an application without paying for unused capacity.
• High-Speed, Deterministic Performance: The integrated NX bus provides ultra-fast, synchronized communication between all connected modules, which is critical for advanced applications requiring precise coordination between logic, motion, and vision.
• Robust and Secure Construction: Engineered with a durable design and positive-lock connectors, it prevents modules from loosening due to vibration and ensures long-term connection integrity in challenging factory conditions.
• Simplified Wiring and Maintenance: The base unit consolidates power and communication distribution, leading to a clean internal layout. Modules can be added or replaced individually without rewiring the entire backplane.
• Seamless System Integration: As the core chassis of the NX ecosystem, the NX-BASE08 guarantees perfect mechanical and electrical compatibility with all NX Series units, ensuring optimal performance and easy engineering.

Application Cases in Various Fields

• Advanced Packaging Machinery: Forms the central rack for a controller coordinating servo-driven form-fill-seal operations, integrating a CPU, digital I/O for sensors, analog I/O for fill control, and a motion control module.
• Semiconductor Handling Equipment: Used in wafer transfer robots, where the base unit hosts a CPU, high-speed digital inputs for position sensors, and specialized modules for interfacing with precision servo drives.
• Automated Assembly and Testing: Serves as the control platform for a multi-station test bench, combining logic control, vision system communication modules, and analog input modules for data acquisition.
• Pharmaceutical Process Skids: Provides a compact, modular control solution for a compact skid, integrating process control, safety I/O, and communication gateways in a single robust enclosure.

Comparison with Competing Products

The OEMAX NX-BASE08 competes with base/rack units from other high-end modular PLC manufacturers like Beckhoff (Bus Terminal mounting racks), B&R Automation (X20 base modules), and Siemens (ET 200SP base units). Its key advantage lies in its integration within the high-performance Omron NX ecosystem, which is renowned for its seamless fusion of logic, motion, and safety. Compared to traditional fixed-I/O PLCs, it offers immense flexibility. Compared to other modular systems, the NX bus and the NX-BASE08 are designed for extremely fast cycle times and tight integration of advanced functions like integrated motion and safety, often in a more compact form factor.

Selection Suggestions and Precautions

1. System Configuration Planning: Before purchasing the OEMAX NX-BASE08, plan your entire module configuration. Map out the required CPU, power supply, and all I/O/special function modules to ensure the 8 slots are sufficient. Remember, the power supply and CPU also occupy slots.
2. Power Supply Calculation: The system power supply (NX-PD) must be selected based on the total power consumption of all modules that will be mounted on the NX-BASE08. An under-sized power supply will cause system faults.
3. Module Placement Order: Follow Omron’s guidelines for module placement order. Typically, the power supply unit must be placed on the leftmost slot (slot 0), followed by the CPU unit. The remaining slots are for I/O and special units.
4. DIN Rail and Environment: Ensure the DIN rail in your panel is sturdy and properly mounted. Verify that the ambient temperature and humidity of the installation location are within the specifications for all components on the base unit.
