D-Series: D074

DIN Panel mount - Level / pump controller

with one control output

The D074 is a basic, panel mount level / pump controller that works with a preset value and two switch points to control a pump or valve. The low and high level switch points are entered as a percentage of the preset value to switch the device on / off. For pump control applications, the function can be inverted to empty a well. A stable level within a hysterese around the preset value is the result.

Advantages
  • Unique, robust IP66, IP67 (NEMA Type4X) panel mount front enclosure made of die cast aluminum, allowing even big jets of water and total immersion.
  • Programming can be done by your own crew with the exact same, plain and sensible menu-driven structure like the F-Series, saving cost and irritation. Know one, know them all!

  • Type: One passive signal output, an active signal output or a robust, highly isolated (NO/NC) relay.

Applications

  • The D-Series is a DIN-sized display and the better alternative for your existing, not waterproof, front panel mount indicators in extreme weather outdoor applications or e.g. in food industries where working environments are often cleaned with powerful water jets.
  • The D074 fits in basic on / off level control applications (e.g. for filling-up a container) without PI(D) control. Also very suitable fwhen the required level changes frequently (e.g. for emptying a well or tank).
