Product Overview

The ALLEN-BRADLEY 1336F-MCB-SP1K is a genuine Main Control Board assembly, serving as the central processing and intelligence unit for the Allen-Bradley 1336 FORCE series Adjustable Frequency AC Drives-6. This sophisticated printed circuit board is the core “brain” of the drive, responsible for executing all critical control algorithms, processing user inputs and feedback signals, managing communication, and generating the control signals that dictate the drive’s output. As a key component in the 1336 Plus II series spare parts catalog, the 1336F-MCB-SP1K is intended for Frame A drives and requires one board kit per drive for proper operation-1.

The ALLEN-BRADLEY 1336F-MCB-SP1K integrates a high-performance microprocessor, memory, and application-specific integrated circuits (ASICs) to perform complex real-time calculations for motor control, including V/Hz, Sensorless Vector, and Flux Vector control modes-6. It interfaces with the operator keypad, accepts analog and digital I/O, manages serial communication via networks like Remote I/O or SCANport, and ultimately commands the gate drive boards to switch the IGBTs, thereby controlling motor speed, torque, and direction with high precision. As the primary logic controller, the functionality of the 1336F-MCB-SP1K is paramount to the entire operation of the 1336 FORCE drive. A failure or fault on this board can render the drive inoperable, leading to unplanned production halts, making the ALLEN-BRADLEY 1336F-MCB-SP1K a critical spare for maintaining industrial operations.
