The ATQ Series Current Transducers sense currents from 0 to 200A and provide a patented proportional frequency output of 0-5 kHz or 0-10 kHz for use with digital-only PLCs. Useful in applications where high resolution sensing or frequency counting is needed, the ATQ Series features a jumper-selectable input and a split-core enclosure for easy installation.
