Isolation And Conversion Of Standard Signals for PCB Assembling
With the Isolation Amplifier DN 240M 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 connector pins - without any further adjustment - Power Supply for 24 V DC
Applicable for standard power supply voltages - 3-port isolation
Protection against erroneous measurements due to parasitic voltages or ground loops - Ultra-small-sized housing
15.5 mm flat module for pcb assembling - Maximum reliability
No maintenance costs - 5 Years Warranty
The Isolation Amplifier DN 240M 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 240M the first choice in customer applications.
Unique in its price class, the DN 240M provides application flexibility thanks to the calibrated range.
The desired input and output range can be easily set by terminal pins and due to the calibrated range selection no further adjustment is necessary.
The flat module with 15.5 mm height for pcb assembling saves space in the customer application.

- 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
