Isolation and Conversion of Standard Signals
With the Isolation Amplifier DN 2000 DRAGO is extending its offer on high-functional and high-reliable components of the interface technique.
- 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 - 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
The Isolation Amplifier DN 2000 is used for isolation and conversion of 0...20 mA, 4...20 mA and 0...10 V standard signals. Due to the calibrated selection of the input and output ranges, the new universal power supply and the ultra-small housing the Isolation Amplifier is suitable for flexible use. The high reliability and the protective separation are further features, which ensure a safe system operation.
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. Also the cut-off frequency can be adapted to the measurement task by using the DIP Switch. Alternatively, all signal combinations are also available in the form of fixed range units.
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. A simple housing latch has been provided for range setting purposes to make all the operating elements, including those on the DIN-rail, easily accessible.
The new universal power pack for 20...253 V AC/DC means the DN 2000 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.
