Digital potentiometers for industrial applications

Sponsored content

A microprocessor-based digital speed potentiometer can directly replace a conventional three-wire analog speedpot or motorized speedpot for most AC and DC drives. The desired set speed is entered into the large .5 in LED display through the convenient front-panel interface, and display units are now programmable for virtually any unit of measure. The attractive panel mount unit is easy to install in industry standard .125 DIN cut-out dimensions. The electrically isolated common signal permits direct wiring from the unit terminal block to the drive’s potentiometer terminal points. The DP4 offers the same enhanced display options and capabilities featured in our other digital control products, as well as the universal power supply and rugged screw type terminal strip.

New feature

The DP4 now offers a configurable input to lock out set point changes via the front panel. This can add an important level of control for safety or system performance reasons. Driven by another customer input, Dart is always looking to make their products better!
