The 424-6512 is a Letourneau two-speed card used in Letourneau industrial drive and motor control system installations. Two-speed control cards manage the selection and controlled transition between two defined speed operating points in drive systems requiring motor speed switching between distinct modes — such as high and low speed settings for different phases of crane lifting, lowering, or positioning operations. Controlled speed transitions prevent mechanical shock loads on the structure, rigging, and mechanical drive train during speed changes in Letourneau’s high-capacity industrial drive applications. Powergenics offers professional repair services for Letourneau drive system control electronics including the 424-6512, restoring proper two-speed selection and transition control functionality.
