Allen-Bradley 2080-LC30-48QBB Micro830 48-Point Programmable Logic Controller

Product Overview

The Allen-Bradley 2080-LC30-48QBB functions as a high-density, standalone programmable logic controller (PLC) within the Micro830 product line. Engineered for standalone machine control applications, this micro-PLC coordinates intricate interlocking logic, high-speed counting, and multi-axis positioning profiles without requiring expansive cabinet spaces.

We provide this industrial processor exclusively as a 100% brand new, original factory-sealed unit. This guarantees untarnished optocoupler isolation circuits, pristine copper terminal landing traces, and unwritten internal flash registers ready for your custom application code via Connected Components Workbench (CCW) software.

Technical Specifications

The table below maps out the precise input/output structures, motion metrics, and physical expansion capacities of the 2080-LC30-48QBB controller:

Engineering Advantages

• Executes Multi-Axis Motion Control without Costly Cards: The processor embeds three dedicated Pulse Train Output (PTO) drivers alongside six high-speed counters directly into the base hardware. This onboard architecture drives stepper motor controllers or servo drives directly via pulse/direction commands, eliminating the need to buy specialized, expensive motion coprocessor cards.

• Maximizes Control Versatility via Modular Front Plug-Ins: Five integrated, front-facing plug-in slots allow control engineers to add analog I/O, extra serial interfaces, or specialized memory modules directly onto the faceplate. This modular layout matches precise application requirements while preserving the original compact panel footprint.

• Simplifies Direct Machine Telemetry Integration: The built-in, dual-protocol RS-232/RS-485 non-isolated serial port establishes quick communication paths with local Human-Machine Interfaces (HMIs) or variable speed drives. The port runs Modbus RTU and ASCII protocols natively to pull diagnostic registers without taxing the main PLC logic cycle.

FAQs

• What is the structural difference between the 24V Source outputs on this model versus a Sink output style?

  The 2080-LC30-48QBB features sourcing transistor outputs. This means the PLC output channel supplies +24V DC power directly to the connected field load (like a solenoid coil or indicator lamp) when energized. The other side of your field load must connect directly to the common DC return rail (0V DC).

• How do I protect the non-isolated serial port from ground loop interference during installation?

  Because this serial port lacks internal galvanic isolation, significant voltage differences between the PLC chassis ground and the connected peripheral device ground can burn out the communication transceiver. Technicians must bond all connected hardware to a common ground bus bar, or deploy an external inline port isolator when routing communication lines over long physical distances.

• Does this controller lose its user program if the main control panel drops power completely?

  No. The Micro830 controller utilizes non-volatile onboard flash memory to store your compiled control program and system parameters securely. It retains the logic application indefinitely across power cycles without requiring an external backup battery pack, though it does require a plug-in real-time clock module if your program tracks precise time-of-day calendars.
