SEM1000 Loop Isolator

Brand: Status Instruments
Favorite
The SEM1000 loop isolator is an ideal solution to overcome ground loops. 

Designed to be series connected into a new or existing (4-20) mA current loop and provide an isolated (4-20) mA signal capable of driving into 300 ohms. The output is powered from the input loop.

This 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.
