Inverse Isolation Amplifier DB 6250
Isolation and Conversion of Industrial Signals with Inverse Characteristic
The Inverse Isolation Amplifier DB 6250 is used for isolation and conversion of industrial signals with inverse characteristic.
- Easy realization of inverse transmission characteristic
Inverse characteristic for unipolar signals can be easily set by using DIP switch - Universal power pack for 20 to 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 bandwidth; high accuracy
No distortion; 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)
Due to the easy selection of the input and output ranges, the new universal power pack and the ultra-small housing the Isolation Amplifier is suitable for flexible use. High reliability and Protective Separation are further characteristics that make the DB 6250 unrivaled.
The order key allows you to select the desired input and output ranges to which the unit will be adjusted at the factory before delivery. These can be easily reconfigured at any time by means of DIP switch settings. Subsequent readjustment or measured range compensation can then be performed at the zero/scan potentiometers on the front panel. Also the cut-off frequency can be adapted to the measurement task by using the DIP Switch.
The small housing with 12.5 mm width saves space in your switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly. For range setting a simple housing unblocking is installed which makes it possible to reach easily all control elements on the mounting rail.
The new universal power pack for 20 to 253 V AC/DC means the DB 6250 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.
