The Allen-Bradley 1336T-MCB-SP51A is a master main control PC board that can be used with the 1336 series of drives, specifically the 1336 FORCE AC drives. It comes in version 5.01 (v5.01) and is compatible with nearly all frame sizes of the 1336 FORCE drives, except the Frame A drives with 0.5 to 20 HP and the Frame G drives with 600 HP. Note that the 1336T-MCB-SP51A Series A main control board is also known as the 74101-772-54 spare part and has an approximate measurement of 12 x 8 x 2.5 inches, as well as a weight of 3 lbs. Make sure to install only 1 1336T-MCB-SP51A main control board per 1336 FORCE drive.

The 1336 FORCE drives are digital AC drives that are controlled by a microprocessor and are field oriented. Its various operations, particularly drive-to-drive interface connections, braking, and encoding, are performed on the 1336T-MCB-SP51A main control board. Among these drives’ standard features are four quadrant operations, nonvolatile parameter storage, high-performance digital velocity loop, runtime accumulator, drive to drive link, fault/warning queues that are time stamped, simplified programming via a parameter table, multiple communication interfaces, reference time stamp, and so many others. For safety, these 1336 FORCE drives come with different protective features, such as ground fault monitoring, programmable stall detection, programmable inverter overload protection, over speed detection, power structure heatsink temperature monitoring, peak output current monitoring, and DC bus voltage monitoring. These drives can operate at temperatures ranging from 0 to 40 °C or 0 to 50 °C, depending on their enclosure.
