Application

  • The 3112 temperature converter measures a standard 2-, 3- or 4-wire Pt100 temperature sensor, and provides an isolated analog voltage or current output.
  • High 3 port isolation provides surge suppression and protects the control system from transients and noise.
  • The 3112 can be mounted in the safe area or in Zone 2 / Division 2 areas.
  • Approved for marine applications.

Technical characteristics

  • Flexibly powered by 24 VDC (±30%) via power rail or connectors.
  • < 30 ms fast response time with simultaneous sensor error detection when selected.
  • Selectable 300 ms response time when signal dampening is needed.
  • Excellent conversion accuracy in all available ranges, better than 0.05% of span.
  • Meeting the NAMUR NE21 recommendations, the 3112 provides top measurement performance in harsh EMC environments.
  • The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
  • A visible green LED indicates operational status of the unit and the input sensor.
  • 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.
