Power supply via the Profibus DP/PA segment coupler. A two-wire
cable according to Profibus specification serves as carrier of both
power and digital data transmission for multiple sensors. The
instrument profile of DPT10 corresponds to profile specification
version 3.0.
The GSD (instrument master files) and bitmap files necessary for
planning your Profibus DP (PA) communication network are available
from the download section on the WIKA homepage www.wika.com
