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

  • The 2-channel version has full galvanic isolation between the channels.
  • Separation of circuits in PELV/SELV installations.
