APPLICATION

  • DRU 414-418 controller can be used to control:

    • a physical quantity (pressure, humidity, etc) measured by an active detector 0...10 V– (B1):

    • or temperature (0 ... 99 °C) measured by a passive detector NTC 10 KΩ ... (B2) with PI command:

  • with PI control mode:

    • progressive 0 ... 10 V–;

    • or three-wire modulating;

    • or On-Off in two stages for two equal loads;

    • or On-Off in three stages for two unequal loads.

  • compatible.

Essential accessories:

  • 1 thermistor type.

Optional accessories:

  • 1 setìpoint adjuster.
