Description
The two-channel TTF300 HART, PROFIBUS PA or FOUNDATION Fieldbus temperature transmitter in proven two-wire technology features a multitude of new functions and enhanced diagnostic information. The field-mount temperature transmitter can be configured via FDT / DTM in DAT200 (Asset Vision Basic) or any standard FTD tool via EDD or local HMI (optional). The Field Information Manager (FIM) is also supported via FDI technology. For PROFIBUS the configuration is possible via GST-file, EDD or DTM and for FOUNDATION Fieldbus via EDD. Two universal sensor inputs, each for RTD, thermocouple, Ω, mV
