Order now the 2080-LC30-24QBB, a high-performance 24-point programmable logic controller from the Allen-Bradley Micro830 series. This controller is designed for large-scale standalone machine control applications that require a higher I/O count and faster execution speeds for sophisticated automation logic.
What Is the 2080-LC30-24QBB?
The 2080-LC30-24QBB is a cornerstone of the Micro830 family, featuring 14 digital inputs and 10 digital sourcing (PNP) outputs. Unlike the Micro820, the Micro830 series is optimized for high-speed motion tasks, including support for up to two high-speed counters (HSC) and pulse train outputs (PTO) for basic axis control. This specific model provides the reliability of transistor-based switching, which is essential for high-frequency operations where mechanical relays would fail prematurely. It features an embedded USB 2.0 port for easy programming and a non-isolated serial port (RS232/485). The 2080-LC30-24QBB architecture supports up to five plug-in modules, offering unparalleled customization for adding analog I/O, specialized communication, or even additional digital points within a compact footprint.

Advanced Motion and Machine Architecture
The 2080-LC30-24QBB architecture is ideal for machine builders who need localized motion control. With its high-speed inputs and outputs, it can interface directly with encoders and servo drives for precise positioning tasks. The five plug-in slots mean that a single 24-point controller can be expanded to handle complex analog sensing or additional communication protocols like Modbus RTU without increasing the DIN rail space. This makes it a preferred choice for material handling, assembly machines, and customized industrial equipment where specialized functionality is required alongside high-speed discrete control.
Installation Advice
When installing the 2080-LC30-24QBB, ensure that you use the dedicated USB port for commissioning to avoid conflicts with the serial network. If you are utilizing the high-speed pulse train outputs for stepper or servo control, use shielded twisted-pair cables and ground them at the PLC side to prevent electromagnetic interference (EMI) from corrupting the pulse signal. Given the 10 sourcing outputs, verify that the 24V DC power supply can handle the peak inrush current of all connected actuators to prevent logic resets during high-load transitions.
Frequently Asked Questions
Q: What is the maximum frequency for the high-speed inputs on the 2080-LC30-24QBB?
A: This controller supports high-speed inputs up to 100 kHz, making it suitable for high-resolution encoders used in precision positioning applications.
Q: Can I use this controller with a 120V AC power source?
A: No, the 2080-LC30-24QBB requires a 24V DC power supply. You can use the 2080-PS120-240VAC external power supply to convert mains AC to the required DC voltage.
