The 414-5331 is a Letourneau speed card used in Letourneau industrial drive and power control system installations for motor speed monitoring and closed-loop regulation feedback. This card processes tachometer or encoder signals from drive motors to provide the Letourneau control system with precise speed measurements used for speed regulation and overspeed protection functions. Speed card failures can cause loss of speed regulation accuracy or defeat overspeed protection in the high-power Letourneau drive systems used in crane, offshore, mining, and heavy material handling applications where mechanical overspeed presents serious safety and equipment risks. Powergenics offers professional repair services for Letourneau drive electronics including the 414-5331 speed card. Call 800-861-9773 for pricing and availability.
