1762-L40BXBR | Allen-Bradley MicroLogix 1200 40-Point Programmable Controller

Product Description

The Allen-Bradley 1762-L40BXBR MicroLogix 1200 is a 40-point programmable logic controller combining digital inputs and outputs for flexible machine control. It includes 24 standard 24V DC inputs, 4 high-speed DC inputs, 8 relay outputs, 7 standard 24V DC FET outputs, and 1 high-speed 24V DC FET output. The controller supports DF1, DH-485, ASCII, and MODBUS communication protocols via serial and programming ports. Designed for reliable operation, it functions in 0–55°C ambient temperatures, withstands 30G shock and 5G vibration, and operates on a 24V DC power supply with 40W typical consumption and 27.9W heat dissipation. Its relay outputs handle 24–125V DC or 120–240V AC with a 10A load, while FET outputs deliver 500–600mA per channel. The 1762-L40BXBR is ideal for small- to medium-scale automation systems requiring precise input/output management and robust communication.
