Allen-Bradley 1762-L40BXB MicroLogix 1200 Programmable Logic Controller

Product Overview

The Allen-Bradley 1762-L40BXB serves as a robust and versatile programmable logic controller (PLC) within the MicroLogix 1200 series. Engineered for small to medium-sized industrial automation applications, this standalone controller integrates 24 DC inputs and 16 mixed relay/FET outputs directly into its chassis. It delivers exceptional flexibility for machine builders, combining high-speed counting capabilities with the ability to drive both AC and DC loads, making it a perfect fit for packaging machinery, conveyors, and process control systems. We supply this item as a 100% Brand New, factory-sealed unit.

Technical Specifications

Engineering Advantages

Versatile Mixed Output Architecture
The 1762-L40BXB eliminates the need for multiple specialized controllers by combining 8 rugged relay outputs with 8 solid-state FET outputs. The relay contacts effortlessly handle AC or DC loads up to 240V AC, while the FET outputs provide rapid switching for DC devices. Notably, the inclusion of a dedicated high-speed FET output allows engineers to implement precise pulse-train motion control or high-frequency signaling directly from the base unit.

High-Speed Processing and Counting
Designed for dynamic industrial environments, this PLC features 4 fast 24V DC inputs capable of operating at frequencies up to 20 kHz. This built-in high-speed capability allows the controller to accurately capture rapid sensor pulses, encoder signals, and flow meter data without requiring expensive add-on modules, streamlining your system architecture and reducing overall hardware costs.

Compact and Expandable Design
Measuring just 120mm x 90mm x 60mm and weighing only 0.65 kg, the 1762-L40BXB fits perfectly into space-constrained control panels. Despite its compact footprint, it supports up to 7 expansion modules, allowing you to scale I/O points as your machine requirements grow. It operates reliably in ambient temperatures from 0°C to 55°C, ensuring stable performance on the factory floor.

FAQs

Q: What is the output configuration of the 1762-L40BXB?
A: This controller features a mixed output configuration consisting of 8 relay outputs (rated for 120-240V AC / 24-125V DC) and 8 solid-state FET outputs (24V DC), one of which is a high-speed output for specialized applications.

Q: Does the 1762-L40BXB support high-speed inputs?
A: Yes, out of its 24 total inputs, 4 are designated as "Fast" 24V DC inputs. These can handle operating frequencies up to 20 kHz, making them ideal for high-speed counting and encoder interfacing.

Q: What type of power supply does this PLC require?
A: The 1762-L40BXB requires a 24V DC power supply (Class 2 SELV) with a tolerance of -15% to +10%. It consumes approximately 82 VA of power during operation.

Q: Can I expand the I/O capacity of the 1762-L40BXB?
A: Absolutely. While it comes with 40 built-in I/O points, the MicroLogix 1200 platform allows you to connect up to 7 additional expansion modules to increase your digital or analog I/O count as needed.
