    Protection against erroneous measurements due to parasitic voltages or ground loops
  • Ultra-small-sized housing
    12.5 mm housing with plug-in screw terminal blocks
  • High accuracy
    No falsification of measured signal
  • Protective Separation
    Protects service personnel and downstream devices against impermissibly high voltage
  • Maximum reliability
    No maintenance costs
  • 5 Years Warranty
    Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)

The Isolation Amplifier DN 2300 is used for electrical separation of 0(4) to 20 mA signals.

The Zero/Span adjustment on the front panel, the new universal power pack, and the compact design all contribute to its application flexibility. High reliability and Protective Separation are further characteristics that contribute to fault-free equipment operation.

The slim housing with 12.5 mm width saves space in the switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly.

The new universal power pack for 20 to 253 V AC/DC means the DN 2300 can be used anywhere in the world, with all mains power supplies. The unit’s high efficiency contributes significantly to reducing the unit’s own heat generation. This is reflected in extremely high reliability and long-term stability. A green LED on the front of the unit has been provided to monitor the power supply.
