YTA70 Temperature Transmitter
Product Details

                                  YTA70 Temperature Transmitter

Features :

The YTA70 is a head mount type of temperature transmitter that accepts thermocouple, RTD, ohms
or DC milivolts input and converts it to a 4 to 20 mA DC signal for transmission. The YTA70 conforms to
the standard DIN form B head mounting. The YTA70 supports HART® communication protocol.
HART protocol revision is selectable from HART 5 or HART 7, and HART 7 features long tag number up
to 32 characters, enhanced burst mode and event notification, and command aggregation function.
