    Advanced features

    • The 5131A transmitter can be configured with the software program PReset using a standard PC and the Loop Link communications unit.

    Application

    • Independent channel jumper selectable inputs for current/voltage or temperature.
    • Current input programmable in range 0...100 mA and voltage inputs in range 0...250 VDC.
    • Linearized, electronic temperature measurement with RTD or TC sensor.
    • Conversion of linear resistance variation to a standard analog current / voltage signal, for example from solenoids and butterfly valves or linear movements with attached potentiometer.
    • 4- or 3-wire connection automatic cable compensation or 2-wire connection with programmable cable compensation.
    • Configurable sensor error detection including NAMUR NE43.

    Technical characteristics

    • Analog current output can be configured to any current within 0...20 mA range.
    • Voltage output range is selectable between 0...10 VDC.
    • Programming can be performed with or without a power supply.
    • The 2-channel version has full galvanic isolation between the channels.
    • Separation of circuits in PELV/SELV installations.
