Overview

The TTH300 is provided for the highest requirements of temperature measurement with two sensor inputs. This supports sensor redundancy and sensor drift monitoring. The transmitter follows NAMUR Recommendations such as NE 89 and NE 107. As an option, an LCD indicator with operating buttons can be connected.
The TTH300 HART can be configured with ABB-tools such as Field Information Manager (FIM), with DAT200 (Asset Vision Basic) via DTM, with a Handheld via EDD, or with any standard tool using FDI-/FDT-Technology.
Transmitter with PROFIBUS PA can be configured via GSD file, EDD or DTM, with FOUNDATION Fieldbus via EDD/CF.
