PR3331, DIN rail temperature converter, loop-powered - isolated

 
  • * Excellent accuracy, better than 0.05% of span
  • * Slimline housing of 6 mm
  • * Excellent EMC performance and 50/60 Hz noise suppression
  • * Selectable < 30 ms / 300 ms response time
  • * Pre-calibrated temperature ranges selectable via DIP-switches


Application

  • * The 3331 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated passive analog current output signal.
  • * High 2 port isolation provides surge suppresion and protects the control system from transients and noise.
  • * The 3331 can be mounted in the safe area or in Zone 2 / Division 2 areas.
  • * Approved for marine applications.


Technical characteristics

  • * Flexibly loop powered by 5.5...35 VDC via connectors.
  • * < 30 ms fast response time with simultaneus sensor error detection when selected.
  • * Selectable 300 ms response time when signal dampening is needed.
  • * Selectable internal/external CJC.
  • * Excellent conversion accuracy in all available ranges, better than 0.05% of span.
  • * Meeting the NAMUR NE21 recommendations, the 3331 provides top measurement performance in harsh EMC environments.
  • * The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
  • * All terminals are protected against overvoltage and polarity error.
  • * High galvanic isolation of 2.5 kVAC.
  • * Excellent signal/noise ratio of > 60 dB.


Mounting / installation / programming

  • * Selectable DIP-settings for easy configuration of more than 1000 factory calibrated measurement ranges.
  • * The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
  • * Wide ambient temperature range of: -25...+70°C
