  • 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 2400 is used for isolation and conversion of 0 to 20 mA, 4 to 20 mA and 0 to 10 V standard signals.

Its high level of reliability and cost optimized design make the DN 2400 the first choice in its class!

Unique in its price class, the DN 2400 provides application flexibility thanks to the calibrated range selection and the new universal power pack.

The desired input and output range can be easily set by using DIP switch and due to the calibrated range selection no further adjustment is necessary.

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. For range selection a simple housing unblocking is installed which makes it possible to reach easily all control elements on the mounting rail.

In cause of the new universal power supply for 20 to 253 V AC/DC the Isolation Amplifier DN 2400 is applicable world-wide for all common supply voltages.
