Allen-Bradley 1336S-MCB-SPI Circuit Board for 1336 PLUS Series

Brand Allen-Bradley

Model Allen-Bradley 1336S-MCB-SPI

Product Overview

The Allen-Bradley 1336S-MCB-SPI is a main control circuit board designed specifically for the 1336 PLUS and 1336 PLUS II adjustable frequency AC drive series. As the central processing and signal interface component, the Allen-Bradley 1336S-MCB-SPI governs the drive’s core control logic, managing everything from motor speed regulation to fault diagnostics. This board serves as the primary interface between the drive’s power structure and external control systems, handling analog and digital I/O, communication protocols, and real-time motor control algorithms.

Engineered for compatibility across drive frames B through H, the Allen-Bradley 1336S-MCB-SPI supports an extensive power range from 0.37 kW to 448 kW, accommodating both small-scale and heavy-duty industrial applications. The board operates on a 5 VDC logic power supply while interfacing with AC input voltages of 200 to 600 VAC and DC bus voltages spanning 310 to 775 VDC. This wide compatibility makes the Allen-Bradley 1336S-MCB-SPI a versatile spare part for maintenance and repair operations across diverse drive configurations within the 1336 PLUS family.

As a discontinued product, the Allen-Bradley 1336S-MCB-SPI is now primarily available through surplus and refurbished channels, serving as a critical replacement component for legacy drive systems still in operation. Its robust design and proven reliability continue to make it an essential part for facilities maintaining Allen-Bradley 1336 PLUS drive infrastructure.
