Introduction to the ABB CP800

Product Description

The ABB CP800 is a central component of ABB’s Compact Product Suite, serving as the power supply and mounting base for various CPU and communication modules in a modular, space-saving automation system. Known as the “Compact Processor Base,” the ABB CP800 provides the physical and electrical backbone for building a flexible and cost-effective PLC solution for small to medium-sized automation tasks. It integrates the power conversion, communication interfaces, and module slots into a single, compact DIN-rail mounted unit. The ABB CP800 is designed to streamline cabinet design by reducing wiring and component count, hosting the CPU, signal boards, and communication adapters directly on its base. This approach simplifies installation and maintenance for machine builders and system integrators. The correct selection and configuration of the ABB CP800 are fundamental first steps in building a reliable control system.

• Mounting: Standard DIN-rail mounting.

• Status Indicators: LED indicators for power, system status, and network activity.

Advantages and Features

The primary advantage of the ABB CP800 is its all-in-one, integrated design that significantly reduces system complexity and footprint. It eliminates the need for a separate, external power supply and complex wiring between the power source, CPU, and communication ports. This integration ensures optimal compatibility and reliability. The CP800 offers a user-friendly design with clear labeling and tool-free or easy-to-use connectors for module installation. Its robust power supply design provides stable voltage even in environments with line fluctuations, protecting the sensitive CPU and I/O electronics. The modular nature of the system built upon the ABB CP800 base allows for easy upgrades and customization.

Application Cases in Industry

This processor base is used across a wide array of industries for machine-level control and small process applications. In factory automation, the ABB CP800 is the core of control panels for packaging machines, conveyor systems, and assembly stations. Within building automation, it powers controllers for HVAC units, lighting control, and access systems. For renewable energy, it serves as the control unit for solar trackers or small monitoring systems. It is also prevalent in water treatment for controlling pumps and valves, and in various OEM machinery where a compact, reliable, and easy-to-install PLC solution is required.

Comparison with Competing Products

Competing products are similar integrated PLC bases or micro-PLC systems from manufacturers like Siemens (SIMATIC S7-1200), Schneider Electric (Modicon M221), and Allen-Bradley (Micro800 series). The ABB CP800 distinguishes itself through its particularly compact and sleek form factor and its deep integration within ABB’s wider automation ecosystem, including drives and robotics. Compared to a traditional setup with a separate power supply, CPU, and communication module, the CP800 offers a more elegant and wiring-efficient solution, though it may offer less flexibility in mixing and matching components from different vendors. Its value is in providing a simple, pre-validated, and robust package for standard applications.

Selection Suggestions and Precautions

Selecting the ABB CP800 requires careful consideration of the connected load. The total current consumption of the chosen CPU module, any added signal boards, and connected sensor loads (if using the integrated 24V supply for sensors) must not exceed the base unit’s power rating. The required communication interfaces (Ethernet, serial) must be present on the chosen CP800 variant. It is crucial to ensure compatibility between the CP800 base and the specific ABB CP-Series CPU module (e.g., CP635-ETH) intended for use.

Precautions:

• Installation should be performed by qualified personnel following ABB’s installation manual and local electrical codes.

• Ensure the input voltage range matches the available line voltage in the cabinet.

• Provide adequate ventilation around the unit to prevent overheating.

• When using the integrated 24VDC supply to power external sensors, ensure the total current draw is within limits and the loads are properly fused.

• Always use the specified CPU and expansion modules designed for the ABB CP800 base to avoid compatibility issues and potential damage.
