Product Overview
The Allen‑Bradley 2080‑LC30‑48QWB is a brick‑style programmable logic controller (PLC) from Rockwell Automation’s Micro830 family—part of the broader Micro800 series—designed for standalone, small‑ to medium‑complexity machine control applications that do not require a full rack‑based PLC system. The 2080‑LC30‑48QWB integrates 28 discrete 24 VDC inputs (configurable as sinking or sourcing) and 20 discrete 24 VDC source‑type transistor outputs (0.5 A per point, 1.0 A max surge) directly into the controller housing, eliminating the need for separate I/O modules or a chassis backplane. This all‑in‑one architecture makes the 2080‑LC30‑48QWB particularly well suited to OEM machines, packaging equipment, conveyors, and standalone process skids where panel space is at a premium and I/O requirements are well defined.Communication and programming are handled through a built‑in USB 2.0 port (for PC connection with Connected Components Workbench – CCW software) and a combined RS‑232 / RS‑485 serial port that can be configured for Modbus RTU master or slave, DF1, or ASCII free‑format messaging—enabling low‑cost connectivity to HMIs, drives, or third‑party devices. The Allen‑Bradley 2080‑LC30‑48QWB also supports up to five 2080 plug‑in modules (smart expansion cards such as additional analog I/O, Ethernet, or extra serial ports) that snap directly into the front of the controller, allowing customized capability without increasing the physical footprint. Two high‑speed counter (HSC) inputs up to 100 kHz and two pulse‑train‑output (PTO) channels for open‑loop stepper or servo positioning further extend the controller’s utility into basic motion‑control domains.Programmed in ladder logic, function block diagram (FBD), or structured text via the free CCW development environment, the 2080‑LC30‑48QWB delivers a cost‑effective, flexible, and expandable alternative to traditional MicroLogix or SLC 500 hardware for new machine designs, retrofit projects, and global OEM exports requiring CE, UL, and cULus compliance in a compact 24 VDC‑powered package.
