A microprocessor based digital speed potentiometer that can 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.
