IsoTrans A 20400

Loop-Powered Isolator for Standard Signals

The first decoupled passive isolator with load stop function to provide protective separation of 0(4) … 20 mA standard signals.

Facts

  • Extremely compact design
    up to 320 channels per meter
  • 1- and 2-channel versions
    cheap and flexible for a wide range of applications
  • Galvanic isolation
    between the input and outpu protection against incorrect measurements  or damage to the equipment due to parasitic voltages
  • Protective separation up to 300 V AC/DC according to EN 61140
    to protect personnel and equipment
  • Load stop function prevents feedback
    e.g. in the case of an open output circuit
  • No power supply required,
    cost saving due to lower wiring effort no mains interference, no unnecessary self-heating and therefore maximum component service life
  • High accuracy
    no distortion of the measurement signal
  • Maximum reliability
    no repair and failure costs
  • International use
    UL / CSA approvals
  • 5-year warranty

Thanks to an extremely high packing density of up to 320 channels per meter of mounting rail and outstanding technical properties such as protective separation, these isolators leave the competition in the dust – even when it comes to the price-performance ratio!
The IsoTrans A 20400 draws its power as a voltage drop directly from the measurement signal without falsifying it. There are no costs for a power supply and wiring. The IsoTrans A 20400 has virtually no self-heating that would cause the electronic components to age faster. Together with a patented circuit design, this means maximum reliability. The consequence of this extraordinary long service life: 5-year warranty!
