The 1761-L32BBB is a programmable controller manufactured by Allen-Bradley/Rockwell Automation as part of the MicroLogix 1000 product line. It has a power supply ranging between 20.4 and 26.4 volts DC with 32 input and output count. It comes in a compact size that allows it to fit in small panel space. The 1761-L32BBB controller requires a smaller panel space as compared to other similar MicroLogix programmable controllers. The module connects to the peer-to-peer network through the built-in RS-232 and DH-485 communication ports. Allen Bradley 1761-L32BBB MicroLogix programmable controller is a hand-held programmer (HHP) that features up to six different languages thus can be used across different parts of the world. This controller is fast and has an execution time of 1.56 milliseconds with an output of 1.85 milliseconds for running a typical 500 instructions program. It has two input options, including analog input or DC and AC for both voltage and current. It also features output options such as MOSFET, relay, TRIAC, and analog outputs for both voltage and current. The controller comes with 43 applied control instructions, 12 basic logic instructions, and 14 advanced application-specific instructions for executing various functions. These controllers, including Allen Bradley 1761-L32BBB controller, provide control capabilities, and they are cost-effective. They also fit well in small spaces and are powerful enough to handle a wide range of applications.

The Allen Bradley 1761-L32BBB MicroLogix 1000 programmable controller has a power supply usage rating of 7 watts at 24 volts direct current (DC). This controller is estimated to operate for a minimum of 50,000 power cycles. This programmable controller is capable of withstanding an operating vibration with a displacement of 0.381 millimeters (0.015 inches) from peak to peak at a frequency range of 5 hertz to 2 kilohertz. It can also withstand a non-operating vibration with a displacement of 0.762 millimeters (0.030 inches) from peak to peak at a frequency range of 5 hertz to 2 kilohertz. Not only can this Allen Bradley programmable controller withstand vibrations, but it can also withstand shocks. The 1761-L32BBB can withstand an operating shock rated up to 10 G at peak acceleration for a duration of 11 milliseconds, plus or minus (+/-) 1 millisecond. It can also withstand a non-operating shock rated up to 20 G at peak acceleration for a duration of 11 milliseconds, plus or minus (+/-) 1 millisecond. When this programmable controller is being operated, it is recommended that the temperature of the surrounding area range from 0 to 55 degrees Celsius (32 to 131 degrees Fahrenheit) or 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) depending on the mounting orientation. When this Allen Bradley programmable controller is not being operated, or is being stored, the temperature of the surrounding area should range from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The humidity levels suitable for this device to be operated ranges from 5% to 95% and should be non-condensing.
