Transmitter repeater for powering and
isolation of 2-,3- and 4-wire transmitters

The Repeater Power Supply IsoPAQ-610 is used to supply and separate 2- and 3-wire SMART Transmitters and active sensor signals with HART communication.

It supplies the transmitter with power and transmits the measuring signal with high accuracy galvanic isolated to the output. Alternative the measuring input accepts active 0/4 … 20 mA signals from 4-wire transmitters.

In addition to the analog signal, the IsoPAQ-610 also transmits data protocols for HART communication. It allows bidirectional communication with the field device from every point of the cabling.

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.

  • Universal operation of SMART Transmitters
    Energization and separation of field located 2-, 3- and 4-wire transmitters
  • 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 installation
  • Optional In-Rail-Bus mounting rail connector
    Allows for fast and economical installation
  • Skyddsseparation enligt EN 61140
    Konstruktionen och den höga isolationsnivån skyddar servicepersonal och enheter nedströms mot otillåten hög spänning
  • Protective Separation acc. to EN61140
    Protects service personnel and downstream devices against
    impermissibly high voltage
