Isolation and Conversion of Standard Signals in Low-cost Applications
With the Isolation Amplifier DN 2400 DRAGO offers a cheap alternative for industrial standard applications.
- Cost optimized design
Economical separation for standard applications - Calibrated signal setting
Input and output range can be set by using DIP switch – without any further adjustment - Universal power supply for 20...253 V AC/DC
Applicable world-wide for all common supply voltages - 3-port isolation
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 - Maximum reliability
No maintenance costs - 5 Years Warranty
The Isolation Amplifier DN 2400 is used for isolation and conversion of 0...20 mA, 4...20 mA and 0...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...253 V AC/DC the Isolation Amplifier DN 2400 is applicable world-wide for all common supply voltages.

- As far as practicable the standards and rules mentioned above are considered by development and production of our devices. In addition the assembly rules for our devices are to be considered by installation in other equipments. For applications with high working voltages, take measures to prevent accidental contact and make sure that there is sufficient distance or insulation between adjacent situated devices.
- Minor deviations possible during interference
