Isolation Amplifier Module DN 240M – Isolation and Conversion of Standard Signals for PCB Assembling


The Isolation Amplifier DN 240M is used for isolation and conversion of 0 to 20 mA, 4 to 20 mA and 0 to 10 V standard signals.

  • Cost optimized design
    Economical separation for standard applications
  • Calibrated signal setting
    Input and output range can be set by using connector pins – without any further adjustment
  • Power Supply for 24 V DC
    Applicable for standard power supply voltages
  • 3-port isolation
    Protection against erroneous measurements due to parasitic voltages or ground loops
  • Ultra-small-sized housing
    15.5 mm flat module for pcb assembling
  • 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)
