Comprehensive Overview of Allen-Bradley 2080-LC50-48QBB Micro850 Controller
The Allen-Bradley 2080-LC50-48QBB is a powerful, versatile programmable logic controller (PLC) from the Micro850 family under Rockwell Automation’s Micro800 series. Designed for mid-range applications, this compact controller provides excellent performance, flexible expansion options, and cost-effective control for a wide variety of industrial automation needs. It is ideal for standalone machines, process control, packaging systems, and small-scale manufacturing setups.
The 2080-LC50-48QBB features 48 built-in digital I/O points, comprising 28 digital inputs and 20 digital outputs. The inputs are 24V DC sink/source configurable, and the outputs are relay-type, allowing them to handle both AC and DC loads. This flexibility in wiring makes it adaptable to different industrial standards and simplifies integration with various field devices such as sensors, pushbuttons, solenoids, contactors, and motor starters.
The controller is equipped with a high-performance 32-bit processor and offers 512 KB of user program memory and 128 KB of data memory, providing sufficient space for complex logic, data handling, and user-defined function blocks. This makes it suitable for applications requiring real-time control, data logging, and custom logic development.
One of the highlights of the 2080-LC50-48QBB is its extensive communication capability. It features:
An integrated EtherNet/IP port for peer-to-peer messaging, remote programming, and HMI/SCADA connectivity.
A USB programming port for easy firmware updates and configuration.
A serial RS-232/RS-485 combo port for Modbus RTU communication with legacy devices or third-party equipment.
Additionally, the controller supports up to three plug-in modules for further customization, such as adding analog I/O, communication ports, or specialty functions like PWM or high-speed counters. It also supports up to four expansion I/O modules, allowing users to scale the system to meet evolving application requirements without replacing the main controller.
The 2080-LC50-48QBB includes a real-time clock (RTC), making it ideal for time-based control applications such as scheduling, logging, or event stamping. This feature is essential in HVAC systems, batch processing, or time-sensitive logic where real-time tracking is needed.
Programming and configuration of the Micro850 controller is done via Connected Components Workbench (CCW), Rockwell Automation’s free software platform. CCW provides a user-friendly interface for ladder logic programming, function block diagrams, structured text, and HMI screen configuration. It also supports online editing, simulation, diagnostics, and firmware management.
Physically, the controller is DIN rail mountable, compact in size, and built with industrial-grade components for rugged performance. It operates in environments with ambient temperatures ranging from -20°C to 65°C, and it is certified for global use with CE, UL, cUL, and RoHS compliance.
The relay outputs of the 2080-LC50-48QBB are especially useful in applications requiring electrical isolation or the ability to switch higher voltages, as they can support a maximum switching voltage of 250V AC or 30V DC. Each output can handle up to 2.0 A, making them suitable for direct actuation of electromechanical devices.
In terms of security, the controller includes features such as password protection and firmware signing, helping to safeguard against unauthorized access and ensuring program integrity, which is vital in sensitive or remote installations.
In conclusion, the Allen-Bradley 2080-LC50-48QBB Micro850 controller offers a powerful blend of performance, expandability, and communication features in a compact and affordable package. With its broad I/O capacity, flexible wiring, and robust programming options, it is a preferred solution for OEMs, system integrators, and end-users looking to implement efficient and scalable control systems in industrial and commercial applications.
