Overview
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.
