      This product is a custom version of the Eco-Line Signal Converter. These are made to your specifications and take longer to manufacture and test.

      The Eco-Line range of signal converters has been designed using a low-cost, powerful microprocessor which enables us to offer flexibility, reliability and accuracy at a really good price in a small package.

      Using miniature DIP switches, a variety of standard inputs and outputs can be selected and with the ‘one button’ calibration, accurate operation in any configuration is assured. Having selected the required input and output ranges, these can be adjusted to be anything within the selected range using the ‘one button’ calibration.

      For example, with a 0 to 100 mV input and ±10V output selected, one can calibrate the device to have say 0 to 60 mV input where 30 mV input gives an output of 0 V, 60 mV an output of +6 V and for 0 mV input and output of – 6 V. Output inversion is also easily accommodated.

      The Zero and Span trimpots can be disabled or switched to a wider adjustment range using the DIP switches. Filtering is also DIP switch selectable in four ranges up to 60 seconds.

      We can also make firmware changes if you have a special application that we have not catered for.
