  • Description

    7500 Series SSI/LDT Interface

    The single slot 7551 Linear Displacement Transducer interface supplies absolute position and velocity data to your programmable logic controller. This module is a direct interface between Balluff, and Temposonics magnetostrictive linear displacement transducers (LDT's) and the Allen-Bradley SLC 500. The 7551 offers programmable position data down to 0.001" resolution. This module also returns velocity data, based on the position scaling in counts per second, and transducer diagnostics.

    For customers seeking a direct interface to most sensors that output SSI data, we offer the 7561 module. The resolution of the 7561 is only limited by the resolution of the sensor that is used. Additional features include: position preset, count direction, and position scaling.

    Both Linear Displacement Transducer modules incorporate diagnostics that constantly monitor system integrity and report any errors to the PLC.
