FLUIDWELL E490P Explosion proof Multi-Purpose Pressure Indicator | Loop Powered | Input Signal 4 - 20mA
The E490 is a multifunctional, loop-powered indicator that can show the loop current, range, and actual process value. The E490 can be used with additional measurement units, such as %, mA, RPM, and even the ability to build a custom unit with a maximum of 8 characters, in addition to its emphasis on level, temperature, and pressure applications. It is easy to choose the measuring unit to be shown using an alpha-numerical configuration menu. The lighting circuit can be powered from the loop by the isolated input circuit. The E490 is capable of receiving 4 to 20mA input signals from a variety of process instruments, such as transmitters for temperature, pressure, level, and flow (square root or linear).

Input | Multi Purpose Inputs Galvanically isolated 4 " 20mA input loop-powered with ultra low voltage drop < 1.5V DC. |
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. |
- In accordance with ATEX and IECEx, explosion proof.
- An indicator powered by a universal loop.
- Galvanically isolated 4–20 mA input signal with an extremely low voltage drop of less than 1.5 V DC makes installation simple in practically any 2-wire, 4–20 mA loop.
- Make a unique measuring unit using no more than eight characters.
- Ex terior enclosure made of premium stainless steel or aluminum.
- Plug and play connectors and a roomy chamber make installation simple.
- The display provides important details quickly, including the loop current, actual value, measurement unit, and a 10-segment bargraph.
- Five big 17.3mm (0.7") digits.
- The LED backlight circuit is independent of the input circuit and can be powered from the loop (voltage drop of 6.5V DC).
- automatic backup of every configuration.
- Aluminum enclosure ambient temperature range: -40°C to +70°C (-40°F to 158°F).
