2-Channel Isolation Amplifier

Isolation and Conversion of Standard Signals

The 2-Channel Isolation Amplifier DN 26000 is used for isolation and conversion of 0/4 ... 20 mA and 0 ... 10 V, 0  5 V standard signals.

  • Calibrated signal setting via DIP switch
    Input and output range can be set by using DIP switch – high precision without any further adjustment
  • 5-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
  • Power supply via In-Rail-connector
    allows 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 2-Channel Isolation Amplifier DN 26000 is used for isolation and conversion of 0/4 ... 20 mA and 0 ... 10 V, 0… 5 V standard signals.

Due to the extremely slim design, the space requirement is only 3 mm per channel. The input and output ranges can be selected individually for each channel via DIP switches. A readjustment is not necessary due to the calibrated measuring ranges. A signal clipping and the cut-off frequency can also be set via DIP switches.

The power is supplied via the In- Rail-Bus, which ensures prewiring on a standard DIN rail. This significantly reduces the wiring effort. A green LED on the front of the unit has been provided to monitor the power supply.
