Programmable HART® isolated 4-20 mA sensor head temperature converter

The TxIsoBlock-HRT temperature converter combines the proven quality of HART® certification with the robustness of THERMO EST devices. Compatible with HART®-certified devices, it features electrical isolation between input and output, resisting surges of up to 1.5 kVeff. Its great asset is its complete configuration via the two 4-20mA current loop wires, offering even greater functionality for device configuration and monitoring.

By using a world-renowned protocol - 40 million field instruments support HART® technology -, the TxIsoBlock-HRT temperature converter allows the use of standardized HART® configuration and supervision software, offering flexibility to users.
