2801-N28 Allen Bradley

Description

Product Name: 2801-N28 Allen Braley Processor module

Product details:  

Allen-Bradley (a brand of Rockwell Automation) is a global leader in industrial automation. Their controller portfolio, primarily known as Programmable Logic Controllers (PLC) and Programmable Automation Controllers (PAC), is designed to handle everything from simple machine control to complex, plant-wide processes.

1. Product Portfolio Overview

Allen-Bradley categorizes its controllers based on the scale and complexity of the application:

2. Key Product Parameters (Specifications)

While specific parameters vary by model, the Logix-based family (ControlLogix & CompactLogix) generally shares these technical attributes:

• Memory Capacity: Ranges from 2 MB to 40 MB+ (e.g., ControlLogix 5580).

• Communication Protocols: Primarily EtherNet/IP (standard), but also supports DeviceNet, ControlNet, and Modbus via modules.

• I/O Capacity: Supports thousands of local and distributed I/O points (up to 128,000 for high-end models).

• Programming Languages: Fully compliant with IEC 61131-3 (Ladder Diagram, Structured Text, Function Block, and Sequential Function Chart).

• Operating Temperature: Standard models operate between 0°C to 60°C; “XT” (Extreme Temperature) versions available for harsher environments.

3. Product Advantages

• Integrated Architecture: A single software environment (Studio 5000) is used for discrete, motion, process, and safety control, reducing engineering time.

• Scalability: You can start with a small CompactLogix and scale up to a massive ControlLogix system without rewriting the core logic.

• Tag-Based Programming: Unlike older PLCs using register addresses (e.g., N7:0), Allen-Bradley uses descriptive tags (e.g., Motor_Start_Pushbutton), making code much easier to read and debug.

• Robust Ecosystem: Seamless integration with other Rockwell products like PowerFlex Drives, PanelView HMIs, and FactoryTalk software.

• Market Dominance: Especially in North America, finding replacement parts and skilled engineers is very easy.

4. Important Considerations (Precautions)

• Power Supply Stability: Always use a dedicated, filtered power supply. Voltage surges can damage the sensitive backplane electronics.

• Electrostatic Discharge (ESD): When handling modules, use an ESD wrist strap. Touching the backplane connectors with bare hands can cause latent hardware failure.

• Firmware Compatibility: The controller firmware version must match the version of the software (Studio 5000) on your PC. Always check the Product Compatibility and Download Center (PCDC) before updates.

• Environment: Ensure proper airflow within the cabinet. Overheating is a leading cause of premature CPU failure.

• Security: As these are connected devices, always implement “Defense in Depth” (CIP Security, physically locking the controller mode switch to ‘Run’).

5. Typical Applications

• Automotive: High-speed assembly lines, robotic cell coordination, and engine testing.

• Food & Beverage: High-speed packaging, bottling lines, and batch processing (CIP – Clean In Place).

• Oil & Gas: Pipeline monitoring, offshore platform safety systems, and refinery process control.

• Water/Wastewater: Distributed pump station control and chemical treatment monitoring.

• Material Handling: Complex conveyor systems and automated storage/retrieval systems (AS/RS).
