DESCRIPTION

The series is a high integration, high efficiency linear active isolation amplifier module, with voltage signal input and current signal output. In the three-wire and four-wire applications, our products largely predigest customers design and helpfully improve the using room ratio of PCB. Adopting electromagnetism isolation technology, it is available to keep higher accuracy and extremely lower temperature drift more than photocoupler isolation. These modules have three-port isolation (input, output and power supply) , and the isolation voltage between them is up to 2.5KVDC.

FEATURES

• Three-port isolation (Between input, output and power supply)

• High accuracy (0.1% F.S.)

• High linearity (0.1% F.S.)

• Isolation voltage (2.5KVDC/ 60s)

• High frequency response

• Extremely low temperature drift (35PPM/

  
  )

• Industry standard (Operating Temperature Range: -25

  
  ~ 71
  
  )

• High reliability (MTBF

  
  500000 hours)
