Separator SGS-61 allows to input full galvanic isolation between transmitter and receiver of 4-20 mA current loop. Additionally it enables a possibility of connecting more than one receiver (e.g. two meters) with common ground in series in one current loop. Thanks to powering directly from current loop the device does not require any additional power supply, and full galvanic isolation allows using it in many applications with high  requirements. Potentiometers which are available from the front, allow to trim minimum current and slope of characteristic, so the correction of whole current loop is possible. The device was built into a very thin housing (6,1 mm) designed for DIN rail mounting, what gives a possibility of its easy application in existing and being assembled systems.
