HART Protocol Transmitter
TxIsoRail-HRT combines the proven quality of HART® certification with the robustness of NOVUS devices. The transmitter is compatible with HART® certified devices and it has electrical isolation between input and output, supporting voltage surges up to 1.5 kVrms. Its great differential is the total configuration through the two 4-20 mA current loop wires, which means more features for device configuration and monitoring.
By using a worldwide known protocol with more than 40 million field instruments supporting HART® technology, NOVUS’s temperature transmitter TxIsoRail-HRT enables the use of standard HART® configuration and supervision software that provides flexibility to users
