Order now the 2080-LC50-48QBB, the high-performance 48-point leader of the Allen-Bradley Micro850 series. Engineered for motion control and advanced networking, this PLC features sourcing transistor outputs and built-in Ethernet, providing the power and scalability required for modern smart machines.
What Is the 2080-LC50-48QBB?
The 2080-LC50-48QBB is a sophisticated programmable logic controller designed for high-speed, standalone automation tasks. It features 28 digital inputs (24V DC) and 20 digital sourcing (PNP) transistor outputs. As a member of the Micro850 family, it is optimized for high-speed motion, supporting up to six high-speed counters (HSC) and three pulse train outputs (PTO) for precision control of servo and stepper drives. The integrated 10/100 Ethernet port supports EtherNet/IP and Modbus TCP, facilitating seamless communication with HMI panels and other controllers in a «Connected Enterprise» architecture. Its expansive I/O can be further increased using five 2080-series plug-in modules and up to four 2085-series expansion I/O modules, allowing the system to grow as machine complexity increases. The transistor outputs are rated for high-frequency switching, making this model superior for applications where mechanical relays would face rapid wear.

Motion Control and System Architecture
The 2080-LC50-48QBB architecture is purpose-built for motion-intensive applications. With three 100 kHz PTO outputs, it can manage multiple axes of motion with high precision. The sourcing output design (PNP) is the standard for modern industrial safety, as it ensures that a short-to-ground will not accidentally trigger an actuator. The controller’s ability to host five plug-in modules allows for the integration of specialized functions like high-speed counters or additional analog channels without expanding the physical width of the PLC on the DIN rail. This density makes it a preferred choice for labeling machines, high-speed assembly lines, and customized robotics.
Expert Tips
For motion control applications using the 2080-LC50-48QBB, ensure that your 24V DC power supply is sized to handle the peak inrush current of all transistor outputs simultaneously. We recommend using a dedicated industrial switch for the Ethernet port to maintain deterministic communication when used in a Device Level Ring (DLR) through a supervisor. Always use shielded twisted-pair cables for the PTO signals to prevent electromagnetic interference from distorting the pulse train, which is critical for maintaining axis synchronization and positioning accuracy.
