The Allen-Bradley 2080-LC50-24QWB is a brick-style programmable logic controller (PLC) from Rockwell Automation's Micro850 series, designed for micro- to small-scale industrial automation applications. This compact controller integrates a power supply, processor, I/O interfaces, and communication ports into a single unit, making it particularly suitable for standalone machine control where space and cost efficiency are critical. With its support for expansion modules and advanced programming capabilities, the 2080-LC50-24QWB is widely used in manufacturing, energy management, and logistics automation. Its robustness and flexibility make it a preferred choice for original equipment manufacturers (OEMs) seeking to balance performance with affordability.
The 2080-LC50-24QWB features 14 embedded inputs and 10 relay outputs, with a 24V DC power supply. Among the inputs, 8 are high-speed channels (inputs 0–7) supporting frequencies up to 100 kHz, while the remaining 6 are standard 24V DC/AC inputs. The relay outputs can handle voltages up to 125V DC with a maximum load current of 2A per point. The controller supports up to 3 plug-in modules, allowing I/O expansion to a maximum of 132 points. It operates within a temperature range of -4°F to 149°F (-20°C to 65°C) and meets IP20 protection standards, ensuring reliability in industrial environments. Communication interfaces include an embedded Ethernet port for Modbus TCP/IP, a USB programming port, and an RS-232/485 serial port.
Programming for the 2080-LC50-24QWB is accomplished using Rockwell Automation's Connected Components Workbench (CCW) software, which supports IEC 61131-3 standard languages such as ladder logic (LD), function block diagram (FBD), and structured text (ST). The controller provides 20 KB of memory for program storage and data handling, enabling the implementation of complex logic, motion control instructions, and PID algorithms. Its embedded Ethernet port facilitates seamless integration with supervisory systems like SCADA or HMI, while the high-speed counter inputs allow for precise monitoring of encoders or frequency-based sensors.
Manufacturing Automation: The controller is used in assembly lines for tasks such as robotic positioning, product sorting, and quality inspection. Its high-speed inputs enable accurate motion control for stepper or servo drives.
Energy Management: In pump stations or compressor systems, the PLC monitors pressure and flow parameters, utilizing PID functionality to optimize energy consumption.
Material Handling: For conveyor belt control in logistics, the relay outputs manage motor start/stop operations, while expansion modules process signals from multiple sensors.
Water Treatment: The device can automate chemical dosing or valve control processes, similar to applications seen with MicroLogix 1400 controllers.
Compared to traditional relay-based systems, the 2080-LC50-24QWB offers higher reliability and flexibility in a compact form factor (90 mm × 158 mm × 80 mm). It provides more advanced communication and motion control features than earlier PLCs like the MicroLogix series, while remaining cost-effective compared to larger controllers such as CompactLogix. The inclusion of diagnostic functions (e.g., I/O status monitoring) supports predictive maintenance strategies, aligning with Industry 4.0 trends.
The Allen-Bradley 2080-LC50-24QWB Micro850 PLC combines compact design, scalable I/O, and robust programming capabilities to address the needs of small-scale automation applications. Its versatility and cost-effectiveness make it an ideal solution for OEMs and system integrators aiming to enhance machine performance while maintaining operational efficiency.
