® IXR100
Isolated, Self-Powered,
Temperature Sensor Conditioning
4-20mA TWO-WIRE TRANSMITTER
FEATURES
q 1500Vrms ISOLATION
q TRUE TWO-WIRE OPERATION :
Power and Signal on One Wire Pair
q RESISTANCE OR VOLTAGE INPUT
q DUAL MATCHED CURRENT SOURCES:
400µA at 7V
q WIDE SUPPLY RANGE 12V TO 36V
q PT100 RTD LINEARIZATION
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.

APPLICATIONS
q INDUSTRIAL PROCESS CONTROL:
All Types of Isolated Transmitters;
Pt100 RTD
Thermocouple Inputs
Current Shunt (mV) Inputs
q ISOLATED DUAL CURRENT SOURCES
q AUTOMATED MANUFACTURING
q POWER PLANT/ENERGY MONITORING
q 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.
