Shunt/mV Isolation Amplifier DS 75000
Isolation and Conversion of Bipolar and Unipolar mV-Signals
The Isolation Amplifier DS 75000 is used for separation and conversion of bipolar and unipolar mV-signals such as those frequently used for current measuring with shunt resistors or other applications with low sensor voltages.
- Calibrated signal setting via DIP switch
Input and output range can be set by using DIP switch – high precision without any further adjustment - High bandwidth; short response time
No signal distortion; no falsification of measured signal - Switchable Zero/Span compensation
For readjustment of the shunt/mV signal or measuring section - 3-Port isolation
Protection against erroneous measurements due to parasitic voltages or ground loops - Extremely slim design
6.2 mm slim housing for a simple and space saving DIN rail mounting - Optional In-Rail-Bus mounting rail connector
allows for fast and economical installation - Protective Separation acc. to EN 61140
Protects service personnel and downstream devices against impermissibly high voltage - 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 input and output range of DS 75000 can be easily set by using DIP switch. Due to the calibrated range selection no further adjustment is necessary.
A switchable compensation of the measuring range can be performed at the Zero/Span potentiometers on the front panel. Also the cut-off frequency can be adapted to the measurement task by using the DIP Switch.
The auxiliary power can be supplied via the connection terminals or via the optional In-Rail-Bus connector. A green LED on the front of the unit has been provided to monitor the power supply.
