Overview
The Allen-Bradley 50914-002 Rev 03 LEM Board is a 96AMP-rated circuit board designed for industrial AC drive and motor control systems. This board functions as a load/error monitor module, providing protection and diagnostic capability in variable frequency drive (VFD) and soft-starter applications. The LEM board monitors current draw and load conditions to ensure safe, reliable operation of connected motor circuits.
Key Features
- 96AMP rated capacity for high-current motor applications
- Revision 03 design with updated protection circuitry
- Load/Error Monitor (LEM) functionality for diagnostic indication
- Direct replacement for equivalent Allen-Bradley drives and starters
- Industrial-grade PCB construction for reliability in harsh environments
Technical Specifications
The 50914-002 is engineered as a control and protection board for AC motor control systems, particularly in the 1334 series drive family and compatible Rockwell Automation drive platforms.
Typical Applications
- Variable frequency drive (VFD) load monitoring circuits
- Soft-starter control boards and diagnostics
- AC motor drive protection and safety systems
- Industrial automation control cabinets
- Machine tool spindle and conveyor drive systems
Compatibility & Replacements
The Allen-Bradley 50914-002 is a standard component in Rockwell Automation’s drive architecture. This part is compatible with Allen-Bradley 1334 series AC drives and related platforms that specify the 50914 board family. When replacing worn or failed boards, verify the revision level (Rev 03) and amperage rating match your system requirements before installation. Consult your drive manual or contact an authorized Allen-Bradley distributor if you require alternate or upgraded board options.
