(4 to 20) mA Ground Loop IsolatorGround Loop IsolatorOutput powered from the input loopHigh AccuracyGalvanic IsolationHigh 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.
