TxIsoRail is fully programmable isolated temperature transmitters dedicated to Pt100 and thermocouple industrial sensors.
TxIsoRail is a DIN rail mount unit. Both units can be easily user configured for input type and working range by means
of an interface cable connected to a PC USB port. Why use isolated transmitters? Isolated transmitters protect the
electrical instruments by eliminating ground loop effects and reduce substantially the undesirable interferences and
instabilities in sensor measurements.
