1762-L40BWA MicroLogix 1200 Controller | Allen-Bradley

Product Overview

The Allen-Bradley 1762-L40BWA functions as a powerhouse within the MicroLogix 1200 family, providing high-density I/O in a compact, cost-effective package. This controller targets applications requiring significant discrete I/O counts without the footprint of a modular rack system. It manages complex logic via 24 onboard 24V DC inputs and 16 robust relay outputs. We offer this unit as 100% Brand New and Original, factory-sealed to guarantee the integrity of your mission-critical automation processes.

Technical Specifications

Engineering Advantages

• Hybrid Input Architecture: The controller combines 20 standard inputs with 4 high-speed "Fast" inputs. These fast inputs interface directly with high-frequency pulse devices like encoders or flow meters, eliminating the need for expensive dedicated counter modules.

• Universal Relay Switching: The 16 relay outputs handle both AC and DC loads across a wide voltage range. This flexibility allows the 1762-L40BWA to switch solenoids, motor starters, and pilot lights directly from the CPU.

• Optimized Thermal Management: Despite the 40-point density, the unit dissipates only 22 Watts of heat. This efficiency prevents thermal buildup in small wall-mount enclosures and extends the lifespan of adjacent electronic components.

• Mechanical Installation Integrity: The terminal blocks support a torque rating of 0.791 Nm. This high clamping force secures wiring against the constant vibrations found in pumping stations and conveyor headers, preventing intermittent signal loss.

FAQs

• Can I expand the I/O capacity of the 1762-L40BWA? Yes. The MicroLogix 1200 bus supports 1762 expansion modules. You simply remove the expansion port cover on the right side of the unit to add analog, digital, or specialty modules to match your evolving system requirements.

• Does this model require a separate 24V DC power supply for logic? No. The 1762-L40BWA accepts 120/240V AC line voltage. It features an internal power supply that energizes the CPU and provides power for the integrated I/O. However, you must provide external 24V DC for the input sensors.

• What is the significance of the 4 "Fast" inputs? Inputs 0 through 3 support high-speed latching and pulse-catching. If your application involves high-speed packaging or counting pulses faster than a standard PLC scan time, these inputs ensure you never miss a trigger event.

• Is the memory non-volatile? The 1762-L40BWA stores the user program in flash memory. While the unit retains the program without power, we recommend using a backup battery (1747-BA) if you need to preserve retentive data values during extended power outages.
