PROTOCONTROL offers Panel Mounting Signal Converter to our clients. These isolators find use in process control industries for signal isolation. Variety of models is available for specific applications. Panel mounting signal isolator is also available.
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.
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.
1) Complete galvanic isolation between input, output and control supply
2) Independent zero and span adjustments
These converters are extensively used in cement, fertilizer, chemical, and processing plants.
Following models are available:
SC I I I D: Signal Converter, Din Rail Mounting, 4-20 mA I/P, 4-20 mA O/P.
