      This product is a variation of the Eco-Line Signal Converter with your choice of a DC voltage input. The output is a fixed 4-20 mA, to choose other inputs or outputs have a look at the fully Customizable Eco-Line.

      Each of these signal converters is configured and burnt in over a 12-24 Hr period. Once burnt in they are then calibrated to ensure accuracy of both the input and the output.

      • Customised input ranges.
      • Selectable filtering options up to 60 seconds.
      • Zero and span trimpots can be locked or disabled using a DIP switch.
      • Wide or normal zero and span adjustment selection using a DIP switch.
      • Input impedance of >100 kS for the voltage input and 50 S for the current input models.
      • Maximum input signals of 100 V for voltage input and 10 A for the current input.
      • Output load >2 kS for the voltage output and 500 S maximum for the current output.
      • Step response approximately 200 ms.
      • Linearity better than 0.1% of full scale.
      • Auxiliary supply 24 VDC or 12 VDC ±5%.
      • Isolation between input, output and auxiliary power supply 1,000 VDC.
      • Operating temperature -10°C to 70°C.
      • 24 hour operational burn-in for every device.
      • Calibration sheet provided for each unit manufactured.
      • DIN rail mounting with dimensions 25 x 80 x 85 mm (W x H x D).
      • Signal conversion, amplification and isolation.
      • Elimination of the effects of ground loops from distributed process signals.
      • Protection of measurement signals against interference such as generated by motors, contactors and power line surges for non-isolated devices and PLC inputs.
      • Process signal amplification in situations where the line impedance is too great to effectively drive the required instrumentation.
