Dart DP4 Digital Speed Pot

The Dart DP4 is a microprocessor based digital potentiometer that will directly replace a conventional 3-wire analog speedpot or motorized speedpot for most AC and DC drives. The desired set speed is entered into the large 1/2 inch 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 1/8 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. The DP4 display is programmable in any engineering unit including Rate, Time in Process and Percent. The DP4 does NOT require encoder feedback. The digital setting is precise and repeatable - great for modernization of existing installations.
