Allen Bradley 2080-LC20-20QBB Micro820 Programmable Controller

Product Introduction

The Allen Bradley 2080-LC20-20QBB Micro820 Programmable Controller is a compact and cost-effective programmable logic controller (PLC) designed for small to mid-sized automation applications. As part of the Micro800 family, it provides a flexible control solution with integrated I/O, making it well suited for standalone machines and simple process control systems.

This controller combines digital and analog capabilities within a single unit, reducing the need for additional expansion modules in many applications. It features built-in 24 V DC digital inputs and outputs, along with analog input channels capable of handling 0–10 V DC signals. The inclusion of analog functionality allows direct interfacing with sensors such as pressure transmitters, level sensors, and variable signal devices.

With fixed terminal connections and a compact footprint, the Micro820 simplifies installation and wiring. Its design focuses on ease of use, reliable performance, and efficient control execution, making it a practical choice for machine builders and system integrators looking for a streamlined automation solution.
