Product Overview

The 2080-LC20-20QWB is a compact, high-performance programmable controller within the Allen-Bradley Micro820 family. Engineered specifically for small-scale standalone machines and remote automation applications, this controller provides a powerful logic engine in a space-saving design. It integrates a versatile mix of digital and analog I/O, including 12 discrete inputs (compatible with both 24V AC and DC signals), 7 robust relay outputs for high-current switching, and onboard analog capabilities (4 inputs and 1 output).

A key advantage of this model is its direct AC power supply, accepting 120V to 240V AC input, which eliminates the need for external DC power conversion in many electrical panels. It features an embedded 10/100 Base-T Ethernet port and a non-isolated RS232/485 serial port, making it an ideal choice for Remote Terminal Unit (RTU) applications and distributed control networks.

Integrated Control and Connectivity

The 2080-LC20-20QWB is built for modern connectivity. Its Ethernet port supports EtherNet/IP for seamless communication with other Allen-Bradley hardware and HMI panels, while also supporting Modbus TCP for third-party integration. The inclusion of a microSD card slot allows for easy data logging, recipe management, and firmware updates without specialized software.

For precision control, the module includes a high-speed pulse width modulation (PWM) output, suitable for driving proportional valves or small motor controllers. The controller is programmed using the Connected Components Workbench (CCW) software, which provides a unified environment for configuration and logic development using standard IEC 61131-3 languages.
