SEM 1000

(4 to 20) mA Ground Loop Isolator

  • Ground Loop Isolator
  • Output powered from the input loop
  • High Accuracy
  • Galvanic Isolation
  • High Reliability

The SEM1000 ground loop isolator is designed to be series connected into a new or existing (4 to 20) mA current loop and provide an isolated (4 to 20) mA signal capable of driving into 300 Ω maximum load.

The output is powered from the input loop.
This ground loop isolator requires no user adjustment during commissioning. Minor adjustments can be made to the calibration of the device by means of the two front panel accessible calibration potentiometers.

Incorrect connection in the loop will not damage the device as long as the specified maximum currents/voltages are not exceeded.
