Order now the 2080-LC30-24QVB, a high-density 24-point programmable logic controller from the Allen-Bradley Micro830 family. This controller is designed for high-cycle industrial applications that require fast execution speeds and the reliability of sinking transistor outputs for automated machinery.
What Is the 2080-LC30-24QVB?
The 2080-LC30-24QVB is a versatile PLC featuring 14 digital inputs and 10 digital sinking (NPN) transistor outputs. Unlike relay-based models, the transistor outputs of the 2080-LC30-24QVB offer nearly infinite mechanical life and can handle high-frequency switching tasks without degradation. This makes it an excellent choice for applications like packaging, labeling, and high-speed assembly lines. The controller architecture supports up to five plug-in modules, offering unparalleled customization for adding analog sensing, extra serial ports, or even specialized memory backups. It features a built-in USB 2.0 port for easy programming and an integrated non-isolated serial port for RS232/RS485 communication, facilitating easy connection to HMI panels and Modbus RTU networks. Its high-speed input capability allows it to interface directly with high-resolution encoders for precise motion and positioning tasks.

Industrial Architecture and Motion Efficiency
The 2080-LC30-24QVB is engineered for motion-intensive standalone applications. Its two 100 kHz high-speed inputs enable accurate speed monitoring and positioning using quadrature encoders. The sinking (NPN) output architecture is commonly used in machinery designed for specific global standards or when interfacing with NPN-compatible actuators. By utilizing the five available plug-in slots, this 24-point controller can be expanded to handle complex process variables without adding side-car expansion modules, keeping the machine control panel as small as possible while maximizing functionality.
Installation Advice
When wiring the sinking outputs of the 2080-LC30-24QVB, remember that the load must be connected between the positive voltage rail and the output terminal. To protect the internal transistors from inductive kickback, always install an external flyback diode across DC solenoid valves or relay coils. During installation, verify that the 24V DC power supply is sized correctly to handle the cumulative load of all 10 outputs. For programming, use a high-quality shielded USB cable to prevent communication dropouts caused by electrical noise from nearby high-power drives.
Frequently Asked Questions
Q: Can the 2080-LC30-24QVB support Pulse Train Output (PTO)?
A: No, the 10-point and 24-point Micro830 sinking/sourcing models do not support PTO. For PTO motion control, you should look at the 16, 32, or 48-point models or the Micro850 series.
Q: What is the purpose of the five plug-in slots?
A: They allow you to add I/O or communication options like a 2080-OF2 for analog output or a 2080-DNET20 for DeviceNet connectivity without changing the physical footprint of the PLC.
