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.

Tech & Buying Guide
Essential Best Practices for PLC Wiring and Installation in Industrial Automation
Successful control system deployment begins with thoroughly reviewing manufacturer technical documentation. Controllers from major brands like Allen-Bradley, Siemens, and Schneider Electric feature unique terminal layouts. Engineers must verify voltage requirements before connecting power cables to prevent catastrophic equipment damage. Standard line connections require strict adherence to regional electrical codes and proper wire color coding. Furthermore, panel builders should always establish a robust low-impedance ground connection using at least 16-AWG copper conductor tied directly to the main plant grounding grid.
