  • Overview

  • Technical details

  •  

    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. As the 3114 is designed with electronics hardware switches, it is not necessary to open the device for setting of DIP-switches.

    Technical characteristics

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