E490 Explosion proof

The E490 is a versatile, 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 E490 can also work with other measuring units, like %, mA, RPM and even the possibility to create a custom unit with max. 8 characters. The measuring unit to be displayed is simply selected through an alfa-numerical configuration menu. The isolated input circuit can power the backlight circuit from the loop. The E490 accepts 4 – 20mA input signals from a wide range of process instruments, including flow (linear or square root), level, pressure and temperature transmitters.

    • Supply

      • Power Supply

        • 4 – 20mA, input Loop-powered, the loop can power the backlight.
        • The E490 can also be powered 9 – 27V DC externally, then the backlight lights up at full intensity and it will not influence the voltage drop in the loop.

      • Sensor Supply

        • None.

    • Hazardous Area

      • Intrinsically Safe

        • For Intrinsically Safe applications we recommend the F-Series.
