Allen-Bradley 2080-LC20-20QBB | Micro820 Programmable Controller

Product Overview

The Allen-Bradley 2080-LC20-20QBB is a compact and cost-effective Micro820 Programmable Logic Controller designed for industrial automation projects. It integrates 12 24V DC inputs, including four configurable analog inputs, and seven 24V DC source outputs, plus one 0–10V analog output.

This controller features embedded Ethernet and RS-232/485 non-isolated serial ports, supporting both TCP and Modbus RTU communication protocols. Its built-in Real-Time Clock eliminates the need for batteries while providing accurate timekeeping for logging and scheduling tasks.

The 2080-LC20-20QBB also includes two plug-in slots, allowing for expansion with additional modules or specialized input/output functionality. The microSD slot supports FAT16/FAT32 for program transfers, datalogging, and recipe storage, making it suitable for remote automation or stand-alone applications.

This module is ideal for controlling valves, solenoids, or temperature sensors through its 5 kHz PWM output and thermistor support for up to four 10k thermistors. The base unit contains a 24V DC power supply, with optional external power via the 2080-PS module for higher requirements.
