Signal Processing Modules

Signal Processing Modules


Signal Processing Modules like converters, isolators and transmitters isolate and convert field signals like Resistance, Current, Voltage, Frequency to 4-20 mA. Signal converter converts field signals received from sensors like RTDs, thermocouples, load cells, and strain gauges to standard 4-20 mA form which is acceptable by PLCs 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. Converters are specially developed to overcome these problems in transmission such as line drop, interference, ground looping and non compatibility to standard processing unit.

  • Cement
  • Fertilizer
  • Chemical
  • Processing plants

  • 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
