DT4200, DT420 E Process Indicators
2Pages

Product features Process Indicators • Display in engineering units • 4-20 mA loop-powered • 4 1/2 digit LCD display (DT4200) • 3 1/2 digit LCD display (DT420 E) • 15.2 mm character height • Min. / Max. values detection 2 isolated limit outputs (DT4200) • Easy on site configuration • IP 65 (front) and IP 30 (rear) protection The DT4200, DT420 E Process indicators enable linear process variables to be displayed in engineering units on the control panel. The unit is loop-powered from 4-20 mA signals, dropping less than 2 V at 20 mA. Two isolated outputs are available with different operating modes for limit signaling or for simple control purposes (DT4200). The process indicators housed in a DIN standard 96 × 45 mm ABS case with IP 65 protection from the front and IP 30 protection from the back side. Large 4 ½ digit (DT4200), 3 ½ digit (DT420 E) 15 mm character height liquid crystal display make process variables easily visible at a distance. A label defining the appropriate engineering unit is attached to the right of the display. The unit can be set up to reverse the display „direction” (i.e. to produce a decreasing displayed value for a rising signal input) and to display a decimal point if required. Easy on-site configuration through the front panel keypad is a major advantage of the microcontroller-based technology. The settings of zero and end-values are non-interactive, making the configuration process rapid and simple. The configuration parameters: scaling, decimal point position, display refresh-rate, signal filtering, (DT4200 limit modes, limit values), etc. are stored in EEPROM. A two level password protects the settings from unauthorised changes. H-1148 Budapest, Fogarasi út 5., Hungary Tel.: +361 460-1000 Fax: +361 460-1001 e-mail: datcon@datcon.hu www.datcon.eu
