DT4200 Process Indicator
Product description
The DT4200 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.
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 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, limit modes, limit values, etc. are stored in EEPROM.
A two level password protects the settings from unauthorised changes.
