The 1336-BDB-SP27A board is a printed circuit board (PCB) that works as a gate drive board on the adjustable frequency drives from the 1336 Plus I, Plus II, Impact, and Force series, specifically the Frame E drives. It has been manufactured and designed by Allen-Bradley and it can be found in the accessories catalog of the 1336 series. It is important to mention that without this board, each one of these drives is unable to initiate operations. This part is related to the start-up of the drive since it controls the input power and the level of frequency the drive uses. The Allen-Bradley 1336-BDB-SP27A printed circuit board (PCB) consists of a circuitry board that is installed on the front panel of the drive behind the main control board. Due to its electronic nature, it must not come into contact with liquids or corrosive materials and it should not be exposed to high levels of humidity. It is recommended to avoid contact with electrostatic discharge sources. When installing this spare part, it needs to be referenced to negative ground.

The Allen-Bradley 1336-BDB-SP27A printed circuit board (PCB) has been designed to support drives with a voltage rating of 230 Volts AC and a Horsepower rating of 75 Horsepower. The default frequency ranges from 50 to 60 Hertz. There are several faults that indicate whether the Allen-Bradley 1336-BDB-SP27A printed circuit board (PCB) needs to be replaced or not. Some of the faults are microprocessor faults, direct faults from the control board, and backlit faults.  The malfunctioning of this drive can also be reflected in drive failures, in the frequency level of the drive, and in the internal power modes.
