Fluidwell D490 | DIN Panel Mount, Intrinsically Safe Multi-Purpose Indicator | Loop Powered, for universal applications, ambient -30°C to +70°C
The D490 is a versatile, panel mount, loop powered multi-purpose indicator to display the actual process value, range and loop current.? Besides the focus on level, temperature and pressure applications, the D490 can also work with other measuring units, like %, mA, RPM and more. The measuring unit to be displayed is simply selected through an alfa-numerical configuration menu. The configuration of Span, offset and number of decimals is done through software functions, without any sensitive dip-switches or trimmers. Typical use: Universal applications where a loop powered, multi-purpose display is required without monitoring function, linearization or signal re-transmitting.
Key features
- Universal loop powered indicator.
- Intrinsically safe according ATEX, IECEx and CSA C-US.
- Input signal: 4 - 20mA with ultra low voltage drop < 1V DC, allowing easy installation in almost any 2-wire, 4–20mA loop.
- Displays the actual value, measuring unit and loop current.
- Very large 26mm (1") high digits.
- Selectable on-screen time units for flow rate: /SEC – /S – /MIN – /M – /HR – /H – /DAY – /D or no unit.
- Number of digits for actual value: 5½.
