SEM1200 Loop SplitterBrand: Status Instruments
The SEM1200 Isolator is a Dual output Isolator, providing two separate isolated (4 to 20) mA current signals from a primary loop. The output loops must be powered externally.
This isolator requires no user adjustment 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.
