Purchase now the 2080-LC30-48QWB, the high-density flagship of the Micro830 family. This 48-point programmable logic controller is engineered for standalone industrial applications requiring extensive I/O capacity and the versatility of electromechanical relay outputs for switching diverse AC and DC loads.
What Is the 2080-LC30-48QWB?
The 2080-LC30-48QWB is a high-performance PLC designed for machine builders who need localized control without the complexity of distributed I/O racks. It features 28 digital inputs and 20 relay outputs, providing a robust interface for complex machinery. As part of the Micro830 series, it focuses on high-speed execution and modularity, allowing for up to five plug-in modules. The relay outputs offer galvanic isolation and can handle up to 2A, making them ideal for driving contactors and solenoids directly. It includes a built-in USB 2.0 port for rapid programming and a non-isolated serial port for RS232/RS485 communication, ensuring compatibility with HMI panels and Modbus networks. Its architecture is optimized for the Connected Components Workbench (CCW) software, allowing for efficient ladder logic and function block development.

Architecture and Machine Scaling
The architecture of the 2080-LC30-48QWB is centered on the «right-sized» philosophy. By providing 48 points on-board, it minimizes the need for external expansion, significantly reducing panel space and wiring costs. The five plug-in slots allow for further specialization, such as adding 2080-RTD2 modules for temperature monitoring or 2080-SERIALISOL for electrically isolated serial communication. This controller is a preferred solution for material handling systems, packaging machines, and large-scale water treatment skids where a high volume of sensors and actuators must be managed by a single, cost-effective unit.
Maintenance Tips
For the 2080-LC30-48QWB, the primary maintenance consideration is relay life. Since it controls 20 relay points, frequent high-speed switching of inductive loads can lead to contact pitting. We recommend using external RC snubbers for AC loads and flyback diodes for DC loads to extend the mechanical lifespan of the module. Periodically check the diagnostic LEDs on the front panel; if the «Fault» LED is active, use the CCW software to retrieve the internal error log, which can pinpoint if a specific plug-in module or the internal backplane has encountered a communication error.
Frequently Asked Questions
Q: Can the inputs on the 2080-LC30-48QWB be used with 5V encoders?
A: No, the digital inputs are rated for 12/24V DC. For 5V encoder signals, you should use a signal conditioner or a specialized high-speed counter plug-in module.
Q: Is the terminal block removable?
A: Yes, the 2080-LC30-48QWB features removable terminal blocks, which facilitates quick hardware replacement without the need to disconnect individual field wires, significantly reducing MTTR.
