The 740101-482-64 is a gate driver board for use by Adjustable Frequency AC Drives manufactured by Rockwell Automation’s Allen Bradley line of factory automation devices. The class of drives that works with this printed circuit board (PCB) accessory include 1336 IMPACT, 1336 PLUS, 1336 FORCE and 1336 PLUS II. The driver board of this caliber operates within voltage power input of 460 Volts AC and outputs 40 Horsepower. This power rating is what makes it different from the gate driver board of part number 1336-BDB-SP55D. The 740101-482-64 can also be assigned an alternative part number of 1336-BDB-SP57D by the manufacturer, and can fit into drives of the frame size designated “C”. This PCB driver, just like the other Gate Board Drivers, is mounted on the main controller board of the drives it functions in. mounting procedures is provided by the manual and should only be done by a qualified technician. The same applies to unmounting and replacement of the gate driver board.

Auxiliary Direct Current power input of +24 Volts is supplied to the 740101-482-64 through a terminal block to back-up the main supply from the mother drive. Several other connectors are available include for expansion of I/O devices. The main danger posed by the Gate Driver Board during installation and servicing is from electrostatic discharge ESD hence the operator should disconnect the main power supply from the drive before embarking on the exercise in additional he or she should check to ensure that there is full discharge on the drive board.
