Purchase now the 2080-LC30-16QWB, a high-performance 16-point programmable logic controller from the Allen-Bradley Micro830 series. This controller is specifically engineered for standalone machine control applications that require the versatility of electromechanical relay outputs to switch diverse AC and DC loads.
What Is the 2080-LC30-16QWB?
The 2080-LC30-16QWB is a compact yet powerful PLC designed for machine builders who prioritize modularity and localized control. It features 10 digital inputs and 6 relay outputs, providing a robust interface for small-to-medium industrial systems. As part of the Micro830 family, it is optimized for speed and flexibility, allowing for the addition of up to two plug-in modules on the front of the unit. These plug-ins can add specialized functionality like analog I/O or extra serial ports without expanding the physical width of the controller. It includes an embedded USB 2.0 port for rapid programming and a non-isolated serial port supporting RS232 and RS485 communication protocols. The architecture is built to work seamlessly with the Connected Components Workbench (CCW) software, offering an intuitive environment for ladder logic, function block, and structured text development.

System Architecture and Machine Scaling
The 2080-LC30-16QWB is ideal for decentralized control strategies where cabinet space is a premium. Its 16-point density often covers all necessary signals for small conveyor systems, automated assembly jigs, or localized pump control. The relay outputs provide physical isolation between the controller logic and field-side power, which protects the PLC from electrical transients. Furthermore, the high-speed input capability allows the controller to interface with encoders for basic speed monitoring or simple positioning tasks, making it a versatile alternative to more expensive mid-range PLCs.
Maintenance Tips
To ensure the maximum lifespan of the 2080-LC30-16QWB, it is critical to manage the mechanical wear of the relay outputs. If switching inductive AC loads, such as contactor coils or solenoids, always install an external RC snubber across the contacts. For DC inductive loads, use a flyback diode. These suppressions minimize electrical arcing, which is the primary cause of contact pitting and premature relay failure. Additionally, ensure the serial port wiring is properly shielded and grounded at one end to prevent communication timeouts in environments with high electromagnetic noise.
Frequently Asked Questions
Q: Can the 2080-LC30-16QWB be programmed via the serial port?
A: Yes, the non-isolated serial port supports programming; however, using the built-in USB 2.0 port is the recommended method for faster data transfer and easier commissioning.
Q: What is the benefit of using plug-in modules with this PLC?
A: Plug-in modules allow you to add features like a 2080-RTD2 for temperature sensing without increasing the DIN rail space, maintaining the compact footprint of your control cabinet.
