Application

  • The 3117 is an isolating converter which can be used for signal conversion of standard bipolar analog process signals into a unipolar analog signal.
  • The unit offers 3-port isolation and provides surge suppression and protects control systems from transients and noise.
  • The 3117 also eliminates ground loops and can be used for measuring floating signals.
  • Mounting of the 3117 can be in Safe area or in Zone 2 and Cl. 1 Div 2 area and is approved for marine applications.

Technical characteristics

  • Flexible 24 VDC (±30%) supply via power rail or connectors.
  • Excellent conversion accuracy, better than 0.05% of selected range.
  • Inputs and outputs are floating and galvanically separated.
  • A green front LED indicates operation status for the device.
  • All terminals are protected against overvoltage and polarity error.
  • Meeting the NAMUR NE21 recommendations, the 3117 ensures top measurement performance in harsh EMC environments.
  • High galvanic isolation of 2.5 kVAC.
  • Fast input to output response time < 7 ms / > 100 Hz – 10 Hz bandwidth damping possible via DIP-switch.
  • Excellent signal/noise ratio > 60 dB.

Mounting / installation / programming

  • Fast and easy configuration of factory calibrated measurement ranges via DIP-switches.
  • A very low power consumption allows DIN rail mounting without the need for any air gap.
  • Wide temperature operation range: -25...+70°C.
