SGM

Current loop supply with ratio function (1-output)
Features:

SGM (1-input 1-output) converts DC current input into isolated DC
voltage/current. This unit can be used as power source for a 2-wiretransmitter (sensors, etc.). Indication displays are equipped.
With the ratio function, this unit can be used in combination withthrow-in type level sensors.
