TxIsoRail Isolated Temperature Transmitter

TxIsoRail is fully programmable isolated temperature transmitters dedicted 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.

  • Programmable input: thermocouples type J, K, T, E, N, R, S, B, Pt100 RTD, 0-50 mV, 0-20 mA, 4-20 mA and 0-10 V
  • User programmable working range
  • 2-wire loop powered 4-20 mA or 20-4 mA output
