Application

  • Linearized, electronic temperature measurement with RTD or TC sensor.
  • Conversion of linear resistance variation to a standard analog current / voltage signal, i.e. from solenoids and butterfly valves or linear movements with attached potentiometer.
  • Power supply and signal isolator for 2-wire transmitters.
  • Process control with standard analog output.
  • Galvanic separation of analog signals and measurement of floating signals.
  • The device can be mounted in Safe area or in Zone 2 and Cl. 1 Div 2. area.

Advanced features

  • When 3114 is used in combination with the 4501 display / programming front and ConfigMate 4590, all operational parameters can be modified to suit any application.

Technical characteristics

  • A green / red front LED indicates normal operation and malfunction.
  • 3-port 2.5 kVAC galvanic isolation.
