2IntroductionThe DP4 digital potentiometer is a compact, microprocessor-based unit capable of being either field orfactory configured for a number of industry's user-interface needs. The DP4 allows the user to adjustthe displayed value via the front-panel push buttons. As the displayed value is raised or lowered, theoutput signal from the DP4 follows proportionally according to the unit's configuration. These unitssupports both unipolar and bipolar output and are capable of automatically inverting, scaling, andoffsetting the output as needed. Utilizing Dart's new modular bus design techniques, the DP4 seriesis ideal for volume OEM applications requiring specialized inputs and outputs. Contact Dart Controls'Sales Department for details. This flexibility makes the DP4 series ideal for applications such as:Water and Waste Treatment SystemsConveyor Oven ControllersSynchronized Conveyor LinesIts durable 1/8 DIN aluminum housings can be easily mounted in a panel or control cabinet. Newoptional pluggable terminal block allows the installer to quickly install or replace units without thehassle of physically removing and reattaching wires. The units can be ordered with either standardEuropean-style terminal block or optional “pluggable” connector.General Features- Microprocessor-based design combines the ultimate in responsiveness and accuracy in one package- Digital front-end ensures long-term accuracy of output signal over time and temperature- Non-volatile memory stores adjustable parameters even when power has been removed- Factory or field programmable via front-panel keypad- Adjustable parameters include display range, output range, output polarity, alarm options, etc.- Internal program-enable jumper selectively prevents tampering with unit’s configuration- Universal power supply accepts line voltages inputs from 85-265VAC @ 50-60Hz without switchesor jumpers. The unit automatically adjusts as needed.- Transient voltage protection prolongs unit's life in harsh industrial environments- Self-contained power supply for external sensor, limited to 5V @ 50mA- Programmable alarm output with Form C contacts rated to 250VAC @ 5A- 1/8 DIN durable aluminum housing for panel mounting.- Large 4 digit, 1/2” LED display- G.E. Lexan membrane and gasket (which are included) meet NEMA 4X standards when used withNEMA 4X enclosures- European terminal block or pluggable terminal block available- Wide operating ambient temperature range of -10C to 45C (14F to 113F)- Multiple operating modes including:• Rate Mode – Displays in rate and non-rate units such as RPM, Gallons per Second, &percent• Time Mode – Displays in time units such as HH:MM, MM:SS, SS:TT, or other unit |
