Get now the 2080-LC30-24QWB, a versatile and robust 24-point programmable logic controller from the Allen-Bradley Micro830 series. Featuring electromechanical relay outputs, this controller is designed for industrial applications that require high-current switching and maximum flexibility across mixed voltage loads.
What Is the 2080-LC30-24QWB?
The 2080-LC30-24QWB is a high-capacity controller within the Micro830 family, providing 14 digital inputs and 10 relay outputs. It is engineered for standalone machine control where multiple output voltages are required, as the dry-contact relays can switch both AC and DC loads independently. This PLC offers a significant step up in I/O count compared to the Micro810/820 series and is optimized for ease of use with its integrated USB 2.0 programming port. The 2080-LC30-24QWB also includes a non-isolated serial port supporting RS232 and RS485 for communication with HMI panels and other controllers. Its modular architecture is a key benefit, supporting up to five plug-in modules, which allows for the addition of analog I/O, RTD sensors, or additional serial ports while maintaining a compact panel footprint. This makes it an ideal solution for conveyors, pump stations, and general manufacturing equipment.

Industrial Versatility and Expansion
The 2080-LC30-24QWB architecture is built for versatility. The relay outputs provide galvanic isolation between the PLC’s internal logic and the high-voltage field loads, which protects the controller from electrical transients. This is particularly useful when controlling AC motors, heaters, or solenoids. With five plug-in slots, this 24-point controller can be customized to handle a vast array of specialized tasks. For example, you can add a 2080-RTD2 module for temperature sensing and a 2080-MEMBAK-RTC for extra memory and clock battery backup, creating a comprehensive control station without the need for external expansion racks.
Maintenance Tips
Because the 2080-LC30-24QWB uses electromechanical relays, it is critical to monitor the cycle count of high-frequency outputs. Relays have a mechanical lifespan that is shortened by heavy inductive loads; always use external surge suppression like RC snubbers for AC or flyback diodes for DC to protect the contacts from arcing. Periodically check the terminal block connections for tightness, as thermal expansion in industrial cabinets can cause screw-clamp terminals to loosen over time. If using the serial port, ensure proper grounding of the cable shield to avoid data corruption in electrically noisy environments.
Frequently Asked Questions
Q: What is the maximum current rating for the relays on the 2080-LC30-24QWB?
A: Each relay output is rated for up to 2 Amps at 120/240V AC or 24V DC, allowing for the direct switching of most industrial contactors and solenoids.
Q: Can I use high-speed counters with this relay-based model?
A: Yes, the 2080-LC30-24QWB supports two high-speed input channels (up to 100 kHz) for feedback, although the relay outputs are not suitable for high-speed pulse train (PTO) control.
