The Allen-Bradley/Rockwell Automation 1336F-BX040-AN-EN4-HASP-L4 controller is an adjustable speed motor controller. The controller has a special rating for its input voltage. The 1336F-BX040-AN-EN4-HASP-L4 controller has an IP00 rating for its enclosure. This type of enclosure provides minimal protection to the controller. The enclosure should, therefore, be used indoors in environments that do not have physical conditions that can pose a threat to the smooth running of the controller. These conditions range include high chances of accidental contact between the controller and solid objects. However, an open enclosure has 1 advantage over other types of enclosures because they allow the 1336F-BX040-AN-EN4-HASP-L4 to be operated at a maximum surrounding temperature of 50 degrees Celsius. Other types of enclosures only allow for a maximum surrounding temperature of 40 degrees Celsius.

By default, the Allen-Bradley/Rockwell Automation 1336F-BX040-AN-EN4-HASP-L4 controller displays programming instructions in English. Alarms, faults, and other textual messages are also displayed in English. The controller can be monitored through the onboard light emitting diodes or by using the human-machine interface module. Note that the 1336F-BX040-AN-EN4-HASP-L4 features a programmer-only human-machine interface module which has an ingress protection rating of IP20. On its control interface, the controller features a TTL (transistor-transistor logic) contact. The logic makes use of bipolar junction transistors. The 1336F-BX040-AN-EN4-HASP-L4 belongs to the Allen-Bradley/Rockwell Automation 1336 PLUS 2 series of motor controllers with an adjustable frequency. Controllers in this series have a minimum output frequency of 0 Hertz and a maximum output frequency of 400 Hertz. Additionally, the 1336F-BX040-AN-EN4-HASP-L4, like other controllers in the same family, has an intermittent overload protection rating of 150% of the rated output for 1 minute at a constant torque.
