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. 0.4mA 0.4mA Optional Offset Adjust 4-20mA 12 O OR 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 instrumentation amplifier with single resistor programmable span and li...
