1762-L40AWA | Allen-Bradley | MicroLogix 1200 Programmable Logic Controller

Product Overview

The 1762-L40AWA serves as a high-density, self-contained controller within the MicroLogix 1200 family. It provides 40 built-in I/O points, making it a cornerstone for medium-scale industrial automation tasks where panel space remains a premium. This unit manages complex machine logic by utilizing 24 digital inputs and 16 robust relay outputs. We offer this product as 100% Brand New and factory-original, ensuring your control architecture benefits from the full lifespan of genuine hardware.

Technical Specifications

The 1762-L40AWA optimizes performance through the following electrical and physical parameters:

Engineering Advantages

• High-Density I/O Footprint: The 1762-L40AWA packs 40 I/O points into a compact chassis. This configuration reduces the need for additional expansion modules, effectively lowering hardware costs and decreasing the overall footprint in crowded control cabinets.

• Universal Power Compatibility: The internal power supply accommodates both 120V and 240V AC nominal inputs. This flexibility allows global deployment of machinery without requiring separate transformers or different regional SKU management.

• Integrated Power for Peripherals: This controller provides dedicated 5V and 24V DC outputs. These power rails support expansion I/O modules and external sensors directly from the PLC, simplifying field wiring and reducing the component count.

• Relay Versatility: The 16 relay contact outputs handle a mix of AC and DC loads. This feature allows the 1762-L40AWA to control various field devices such as solenoids, motor starters, and pilot lights without the need for interposing relays.

FAQs

• Does the 1762-L40AWA require a separate battery for memory backup?

  The MicroLogix 1200 uses flash memory for program storage. While the unit maintains the program without power, we recommend using the optional 1747-BA battery if your application requires long-term retention of volatile data values during extended power-down periods.

• Can I expand the I/O beyond the 40 built-in points?

  Yes. You can expand the controller’s capability by adding 1762 series expansion I/O modules to the right side of the base unit. The 1762-L40AWA supports up to six expansion modules.

• What is the correct way to handle high inrush current during startup?

  This unit draws up to 40 Amps of inrush current at 240V AC. Ensure your upstream circuit breakers and power distribution components account for this short-duration spike (4-8 ms) to prevent nuisance tripping during system initialization.

• Are these units refurbished or new-old-stock?

  We guarantee every 1762-L40AWA unit is 100% Brand New. These are original Allen-Bradley products in their factory packaging, ensuring the relay contacts and internal capacitors have zero prior operational wear.
