Gray Single Processing Modules

PROTOCONTROL export, manufacturing & supplying Single Processing Modules from Pune, Maharashtra, India. These isolators find use in process control industries for signal isolation. Variety of models is available for specific applications. Signal converter converts field signals received from sensors like RTD, Thermocouple, load cells, strain gauge to standard 4-20 mA form which is acceptable at PLC or DCS for further processing.
Transmitters are generally head mounted and fitted in the head of temperature sensor, Isolators provide further isolation of field signal so that PLC side is isolated from field side.

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, 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.
