IXR100

The IXR100 is an isolated 2-wire transmitter featuring loop powered operation and resistive temperature sensor conditioning (excitation and linearization).

The IXR100 contains a DC/DC convertor, high accuracy instrumentation 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 temperature transmitters as well as rack and rail mounted equipment.

The isolated two-wire transmitter allows signal transmission and IXR100 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.
