Introduction; General Features - DART Controls DP4 CONTROL Serie Manual De Instrucciones

The DP4 digital potentiometer is a compact, microprocessor-based unit capable of being either fi eld or
factory confi gured for a number of industry's user-interface needs. The DP4 allows the user to adjust
the displayed value via the front-panel push buttons. As the displayed value is raised or lowered, the
output signal from the DP4 follows proportionally according to the unit's confi guration. These units
supports both unipolar and bipolar output and are capable of automatically inverting, scaling, and
offsetting the output as needed. Utilizing Dart's new modular bus design techniques, the DP4 series
is ideal for volume OEM applications requiring specialized inputs and outputs. Contact Dart Controls'
Sales Department for details. This fl exibility makes the DP4 series ideal for applications such as:
Water and Waste Treatment Systems
Conveyor Oven Controllers
Synchronized Conveyor Lines
Its durable 1/8 DIN aluminum housings can be easily mounted in a panel or control cabinet. New
optional pluggable terminal block allows the installer to quickly install or replace units without the
hassle of physically removing and reattaching wires. The units can be ordered with either standard
European-style terminal block or optional "pluggable" connector.
