    7700 Series LDT Interface

    The 7751 and 7752 LDT modules are direct interfaces between magnetostrictive linear displacement transducers (LDT's) and the Allen-Bradley 1771 I/O system. These modules interface with digital Start/Stop or PWM transducers. Fully programmable from the backplane or the sealed keypad and display, these modules provide absolute linear position and velocity data. The 7700 offers programmable position data down to 0.001" resolution. MTS and Balluff offer LDT transducers are available in lengths from 2 to 140 inches in a variety of mounting styles.
