Isolation Amplifier DN 25000 Isolation and Conversion of Standard Signals


The Isolation Amplifier DN 25000 is used for isolation and conversion of 0/4 to 20 mA and 0/2 to 10 V standard signals.

  • Calibrated signal setting
    Input and output range can be set by using DIP switch – high precision without any further adjustment
  • 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
  • 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)

The input and output range of DN 25000 can be easily set by using DIP switch. Due to the calibrated range selection no further adjustment is necessary. Also the cutoff 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.
