2-wire programmable transmitter

5131B

The 5131 transmitter can be configured with a standard PC and the Loop Link communications unit.

Independent channel jumper selectable inputs for current/voltage or temperature.
Current input programmable in range the 0...100 mA and voltage inputs in the 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 with automatic cable compensation or 2-wire connection with programmable cable compensation.
Configurable sensor error detection including NAMUR NE43.

The 2-channel version has full galvanic isolation between the channels.
Separation of circuits in PELV/SELV installations.
I.S. barrier for temperature sensors, potentiometers and current / voltage signals.
