The SEM1200 is a current loop splitter and isolator, providing two separate isolated (4 to 20) mA current signals from a primary loop. The output loops must be powered externally.
This current loop splitter 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.
