An Allen Bradley product, the 1762-L40BWAR was designed to be a Programmable Logic Controller, or PLC. This controller is part of the MicroLogix 1200 series of products and can ideally be used in projects that require implementing micro and small automation requirements. The 1762-L40BWAR includes two (2) communication interfaces on the front panel, as well as the left panel. Additionally, both of the communication ports are mini-DIN circular connectors with eight (8) pins. For primary communications, the front panel port is defined as the primary port that allows for communication with all of the programming workstations, including HMI, or human machine interface, and SCADA, or supervisory control and data acquisition, systems. The other port is the programming port which is only used for programming of controllers, online edits, and testing. These ports function simultaneously.

The Allen Bradley 1762-L40BWAR programmable logic controller has embedded I/O channels. These channels consist of twenty (20) standard 24-volt direct current (DC) inputs, four (4) fast 24-volt direct current (DC) inputs, and sixteen (16) relay outputs. The 1762-L40BWAR is powered via an external voltage that ranges from 100 to 240 volts AC at a frequency range of 47 to 63 hertz. The power supply inrush rating of this device at 120 volts AC is 25 amperes for 8 milliseconds, while at 240 volts AC, the power supply inrush rating is 40 amperes for 4 milliseconds. The power supply usage rating of this PLC is 82 volt-amperes. This device has physical dimensions that measure 90 millimeters x 160 millimeters x 87 millimeters (height x width x depth). With the DIN latch open, the physical dimensions measure 104 millimeters x 160 millimeters x 97 millimeters.
