2 Wire Loop Power Isolator 270i

The 270i accepts a process current input and provides an isolated 4-20mA process output signal. Power is received form the input signal current. The 12 to 50V DC @ 20mA is loop powered and a 1500V AC peak isolation DC prevents ground loops from occurring.

The Acromag 270i is a Loop Power Isolator 2 Wire 4-20mA.

Firstly, this mode uses transformer isolation. Which effectively breaks the electrical path between transmitted signal and receiving device. This eliminates ground loops, reduces noise and protects against transients for more accurate and reliable measurements.

Secondly, this product is easy to install. All units are factory calibrated for loads up to 600 ohms. This eliminates any need for load trim adjustments.

Other outstanding features of the 4-20mA Loop Power Isolator include:

  • Accurate and Stable to provide reliable measurements in harsh environments
  • 1500V AC Peak Isolation (250V AC or 354V DC Continuous) prevent ground loops
  • RFI and Emi resistance which minimises the effects of environmental noise
  • Calibration is independent of the load and eliminates load compensation adjustments
  • Zero and span adjustment enable precise calibration
  • Compact house uses less space for easier installation into control panels
  • Input current sense resistor simplifies field diagnostics
  • Operation temperature range is -25° to 85°C
