It is designed to fit into the 1762 expansion I/O chassis, which serves as a rack for housing multiple modules.

The "L40" in the module's name indicates that it has 40 digital inputs/outputs (20 inputs and 20 outputs) built into the unit.

The "BX" in the module's name indicates that it includes a built-in power supply to provide 24V DC power to the module and connected devices.

The "BR" in the module's name indicates that it has a real-time clock feature, allowing it to keep track of time and date.

The module supports various communication protocols, such as RS-232, RS-485, and Ethernet/IP, providing options for communication with other devices or systems.

It can be programmed using Rockwell Automation's RSLogix 500 programming software, which allows you to create ladder logic programs to control and monitor the connected devices.
