Product Profile of Loop Powered Isolator
OSNA is , a New Delhi-based manufacturer. Osna Electronics, offers manufactures loop-powered isolators. These loop power isolators enable the users to avoid running an additional 24 V DC power supply. Some of the technical features of these loop power insulators are:These use the loop energy to transform and isolate the incoming field signal. High density of isolating 3 channels of a 420 mA signals is achieved in a single 17.5 mm housing, or an 8 channel isolation in an EURO card; . The most economical method of attaining galvanic isolation between incoming field signals from sensors and the PLC or DCS is achieved by soldering the loop-powered isolator modules onto the standard printed circuit boards. Precision dimensioning of the loop-powered isolator allows it to draw a very minimum of power for isolation from the incoming signal without appreciable distortion to the signal. By using very low loss troidal transformers and a patented OSNA circuitry, A 0.1 percent transfer accuracy is achieved by using very low loss troidal transformers and a patented OSNA circuitry.
