TT7S00-HR
TT7S00-HR is an non-isolated two-wire transmitter which converts the
measuring signal of a 3-wire Pt100 RTD into a standardized load-
independent, 4-20 mA current which is linearly proportional to the
measured temperature.
Multi range design with solder pads and potentio-meters.
Flat design gives easy access to terminals and adjustments.
Only 6.5 V voltage drop over the transmitter allows for high loads in the 4-
20 mA output loop.
