1 SINEAX VK 66 Programmable Temperature Transmitter, for RTD and TC inputs, with PROFIBUS PA protocol for installation in the terminal head of a temperature sensor DIN 79, Shape B extra high 00 II () G Application SINEAX VK 66 is a two-wire head-mounted transmitter head. It is designed for measuring temperature in combination with thermocouples or resistance thermometers. Thermocouple nonlinearities are automatically compensated. The output signal is superimposed on the power supply current (Manchester code) according to specification IEC 58-. The communication protocol used is Profibus PA Profil Version.0. The measured variables and ranges can be configured and set on a PC (Master Class ) running the respective configuration software. Fig.. Measuring transmitter SINEAX VK 66 with PROFIBUS PA protocol.

The hardware required includes an RS 85 cable (PC bus coupler), a bus coupler and an ancillary two-wire cable. The connections between Master Class bus coupler SINEAX VK 66 can be seen from Fig.. The bus coupler compensates the level between RS 85 and IEC 58- and also establishes the power supply connection between the Master Class and the SINEAX VK 66 transmitter.
