Allen-Bradley 2080-LC20-20QWB Programmable Logic Controller

The Allen-Bradley 2080-LC20-20QWB is a Micro820 programmable logic controller designed for compact machine control with 20 I/O points, comprising 12 digital inputs and 7 relay outputs plus 1 analog output for basic process control. It includes Ethernet/IP (ENET/IP) connectivity for networked control and remote I/O, and runs on a 10–30 V DC supply. The digital inputs are arranged as four non-isolated 24 V DC sink inputs (Inputs 00–03) and eight isolated inputs (Inputs 04–11), with input voltage ranges of 9.8–26.4 V DC for non-isolated and 10–30 V DC for isolated inputs. The 7 relay outputs switch DC loads, while the 1 analog output provides a simple analog signal channel for proportional control or monitoring. The compact housing measures 3.54 in high, 4.09 in wide, and 2.95 in deep (approximately 90 x 104 x 75 mm), making it suitable for space-constrained panels and small automation tasks such as packaging lines, conveyors, and basic machine sequencing. Programming is performed with Rockwell Automation’s Connected Components Workbench (CCW), enabling ladder logic or function-block style programming and straightforward integration with other Rockwell components in a compact control solution.
