Keeping in view the increasing and changing requirements of our valued customers, we are actively involved in offering a broad range of Signal Conditioning Modules in the market. The basic material applied in the development of these products is provided by genuine, authentic and certified vendors of the industry after conduction rigorous examinations on the used raw inputs. Moreover, these products undergo various quality checks during the manufacturing process to maintain their supremacy as per the industry.


  • Improve signal communication
  • Pressure Transmitter
  • Signal Repeater

Signal Transmitters:

  • The purpose of current signal transmission is to achieve immunity to level drops from long runs and noise from motors relays, actuators, transformers, switches, etc. Normally, these are built-in transducers.

Signal Isolators:

  • The purpose of galvanic isolation is to overcome ground-loop problem and to isolate high voltage plant side from the low voltage computer side/ Instrumentation panel side. This current signal is used in control room for the indication, control, data logging, data processing ,etc. In case of isolators, normally output parameter is the same as the input parameter and more number of outputs with a single input is available.

Signal Converters:

  • Converts various field signal from RTD, thermocouple or other signals like current, voltage , frequency, resistance or any other parameter into electrical parameter. In this case,output parameeter is normally not same as input Parameter. Both isolated and non-isolated versions available.
  • Signal-Conditioning

Common Specifications:

  • Galvanic Isolation : 500 V DC/ 1KV RMS(In case of isolators )
  • Working Temp. : 10 To 50 C
  • Storage temp. : 70 C
  • Linearity Scale : Better than 0.3% over full
  • Instrument Accuracy Scale : Better than 0.3% over full
  • Zero and Span adjustment : Provided by means of trim-pot(external/internal)
  • Termination : Suitable for 2.5 mm square conductors
  • Supply voltage : 110V / 230 V DC/AC

Product Details:
ApplicationElectrical Isolators

Our in-depth knowledge and vast industrial expertise enable us to provide a distinguished collection of Electrical Isolators. Offered products are designed and verified under the firm direction of well qualified professionals. For strictly adhering to the industry accepted norms, this product is thoroughly tested by best quality controllers at every stage of production process. In line with clients' variegated requirements, we are offering the entire range in variety of modified options.


  • Low maintenance
  • Precisely designed
  • Fine finish

Other Details:

  • It is a unit that accepts most common high level process signals ( current and voltage),isolates them electrically and galvanically without changing the output parameters
  • Input and output are thus same and isolation is provided by the circuitry.
  • Isolates field signals from control room instruments. Eliminates ground loop problems
  • Makes weak field signals immune to level drop due to long run and noise
  • Optional facility provided to measure loop current. This special facility is useful to calibrate the instrument on line without disturbing the loop and thus the process
  • Multiple outputs models available for independent processing

Solators are available in several versions depending upon the nature of input and No. of outputs:

  • SI-1 : It provides single output from a single input
  • SI-2 : It provides two isolated outputs from a single input
  • SI-3 : It provides three isolated outputs from a single input
  • SI-4 : It provides four isolated outputs from a single input
