Description
Our range of signal converters provide a convenient way of converting almost any input voltage or current to commonly used process signal levels. Voltages of down to 50 mV can be converted to a standard current or voltage output. Customized input and output requirements can usually be met on request. A high quality instrumentation amplifier forms the input stage with galvanic isolation between input and output. A filter with adjustable time constant between 0 and 20 seconds is also provided for the filtering of noisy signals.

Applications
- Signal conversion.
- Filtering of noisy signals.
- Elimination of the effects of ground loops from distributed process signals.
- The protection of signals against common mode interferences such as motors, contactors and power line surges.
- Process signal amplification in situations where the line impedance is too great to effectively drive the required instrumentation.
