Allen-Bradley 1762-L40BWA MicroLogix 1200 Programmable Logic Controllers
The Allen-Bradley 1762-L40BWA is a 40-point programmable logic controller module belonging to the MicroLogix 1200 platform. Powered by an integrated 120-240 VAC power supply, it features 24 digital 24 VDC inputs and 16 electromechanical relay outputs to handle discrete automation and machine control. Equipped with a 6,000-word non-volatile memory, screw terminal blocks, and dual mounting flexibility, this controller provides a self-contained processing and I/O solution for standalone machinery and process control systems.
Integrated Digital I/O and High-Speed Signal Processing
The 40-point I/O architecture includes 20 standard 24 VDC digital inputs alongside 4 fast 24 VDC inputs designated for high-speed pulse processing, such as encoder feedback or event counting. The digital input channels support sink or source wiring topologies to accommodate a variety of field sensors. For field actuation, 16 relay outputs provide mechanical switching, enabling direct interface with external contactors, solenoid valves, and indicator lamps.
System Mounting and Physical Configuration
Designed for industrial enclosure installation, the 1762-L40BWA supports both standard 35 mm DIN rail mounting and direct panel mounting using mounting screws. Connections for power, input sensors, and output loads are made through integrated screw terminal blocks, allowing for secure field wiring. The compact enclosure weighs 1.59 lbs (0.72 kg) and incorporates a front panel access cover for I/O expansion module connection.
