APPLICATIONS

INDUSTRIAL PROCESS CONTROL:

All Types of Isolated Transmitters;

Pt100 RTD

Thermocouple Inputs

Current Shunt (mV) Inputs

ISOLATED DUAL CURRENT SOURCES

AUTOMATED MANUFACTURING

POWER PLANT/ENERGY MONITORING

GROUND LOOP ELIMINATION

The isolated two-wire transmitter allows signal trans-

mission and device power to be supplied on a single

wire-pair by modulating the power supply current

with the isolated signal source. The transmitter is

resistant to voltage drops from long runs and noise

from motors, relays, actuators, switches, transformers

and industrial equipment.

It can be used by OEMs producing isolated transmitter

modules or by data acquisition system manufacturers.

The IXR100 is also useful for general purpose isolated

current transmission where the elimination of ground

loops is important.

DESCRIPTION

The IXR100 is an isolated 2-wire transmitter featuring

loop powered operation and resistive temperature

sensor conditioning (excitation and linearization).

It contains a DC/DC convertor, high accuracy instru-

mentation amplifier with single resistor programmable

span and linearization, and dual matched excitation

current sources. This combination is ideally suited

to a range of transducers such as thermocouples,

RTDs, thermistors and strain gages. The small size

makes it ideal for use in head mounted isolated tem-

perature transmitters as well as rack and rail mounted

equipment.
