Product Overview

The ALLEN-BRADLEY 1336F-MCB-SP1G is a Main Control Board (MCB) designed as the central processing and communication hub for the Allen-Bradley 1336 PLUS II and 1336 FORCE series of adjustable frequency AC drives -5. This critical printed circuit board serves as the “brain” of the drive system, housing the primary microprocessor, non-volatile memory, and core logic that governs all drive functions including control algorithms, I/O signal processing, parameter storage, and network communication -5. The ALLEN-BRADLEY 1336F-MCB-SP1G specifically supports drive frames B through G, with the -SP1G suffix indicating a particular revision and firmware configuration optimized for specific drive ratings and application requirements -2-5.

Engineered for demanding industrial environments, the ALLEN-BRADLEY 1336F-MCB-SP1G executes sophisticated control algorithms such as Volts/Hertz and sensorless vector control, enabling precise speed and torque regulation for industrial motors. Without this board, a 1336 series drive cannot be configured, controlled, or operated -5. The ALLEN-BRADLEY 1336F-MCB-SP1G offers comprehensive connectivity options, including a snap-in Human Interface Module (HIM) for local programming and monitoring, and supports networking protocols such as Remote I/O (RIO) and DeviceNet through plug-in communication daughterboards -1-2-5. This versatility allows the ALLEN-BRADLEY 1336F-MCB-SP1G to integrate seamlessly with Allen-Bradley PLC systems, HMIs, and supervisory control architectures. Today, as a discontinued legacy component, the ALLEN-BRADLEY 1336F-MCB-SP1G is primarily available as a replacement part, vital for maintaining operational continuity in systems where the 1336 series drives remain active -2.
