Protocontrol Instruments Signal Isolators

Listing ID #512251

We offers signal isolators to isolate and convert field signals like resistance, current, voltage, frequency to 4-20 ma. These isolators find use in process control industries for signal isolation. Variety of models is available for specific applications.
transmitters are the field devices which receives signal from field sensors like temperature sensor (pt 100, thermocouple) or load cell & convert these in suitable form like 4-20ma, o-20 ma, 0-10v as an input for panel instruments.in the field, many signals are generated such as motor current, armature voltage, position feedback in the form of change in resistance or signals obtained from various types of traducers in standard voltage or current form. these signals are not isolated from input and not suitable for transmission over long distance. Converters are specially developed to overcome these problems in transmission such as line drop, interference, ground looping, and non compatibility to standard processing unit.
salient features includes complete galvanic isolation between input output and control supply , independent zero and span adjustments ,stable current output eliminates need for special cable, shielding,
the isolators are housed in din rail mounting engineering plastic enclosure. Special robust cast al. Enclosures suitable for field mounting are also available.
these isolators are extensively used in cement, fertiliser, chemical, and processing plants.
