SEM1010 Isolating Repeater

Brand: Status Instruments
Favorite
The SEM1010 is designed to provide an isolation barrier between a field mounted (4-20) mA transmitter and the process monitoring system.

The isolator output is a two wire (4-20) mA current sink. The SEM1010 derives it’s power from the output loop.

This isolator requires no user adjustments during commissioning, apart from an initial test, to ensure it operates correctly over its full working range. 

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.
