The Allen-Bradley 2080-LC50-24QVB is a Programmable Logic Controller (abbreviated to PLC) from the Micro850 controller series. This PLC is from an economical segment; this product is designed to work on low-cost, standalone machines. The 2080-LC50-24QVB is one of the more prominent representatives of this series, with advanced functions that can be delivered at a low cost. The 2080-LC50-24QVB PLC can be expanded with a maximum of four expansion I/Os (132 I/O points maximum); it can also support communication connections through implanted Ethernet port. Removable Terminal Blocks (RTB) can contribute to the easy installation of the device.

The 2080-LC50-24QVB comes with the following options: high-speed input interrupts, 3 base plug-in slots, Modbus/TCP support, Modbus RTU protocol, CIP Serial support, and the serial ports RS232 and RS485. This PLC receives and sends information via 14 inputs at 24 Volts AC/DC and 10 relay outputs (1A per point), and its work state is visualized over status lamps: power, input, output, fault, run, module, serial COM, network and force status. The 2080-LC50-24QVB is programmed in one of three ways; a Function Block Diagram (FBD), Structured Text Language (STL) or with a Ladder Diagram. The 2080-LC50-24QVB, like all Micro800 controllers, has a USB interface that enables easy programming of the device. A user can apply a standard USB A male to B male cable, though the serial and USB cables are not to exceed 3.0 meters (9.84 feet).

Up to 256 programs are performable in a single project on this unit. This PLC contains a project memory with a copy of the complete downloaded project, which also contains comments. Configuration memory with setup information is saved in a project memory as well. Password protection for a project download is available. This device has dimensions of 90 x 158 x 80 millimeters (3.54 x 6.22 x 3.15 inches), and a shipping weight 0.423 kilograms (0.933 pounds). Its wiring requires minimum and maximum sizes of 0.2 millimeters 2 to 2.5 millimeters 2, and the enclosure has an IP20 rating. The input circuit of this module is 24 Volts DC sink/source for both standard and high-speed operations, while the output circuit is approximately 24 Volts DC sink, also for both standard and high-speed applications. This module requires an overall power supply of 24 Volts DC while consuming around 28 Watts of power on average. Installation note: keep this unit spaced out from objects, allowing a minimum of 2 inches of space on all sides for suitable ventilation.
