The YTA50 is a head mount type of temperature transmitter that
accepts thermocouple or RTD input and converts it to a 4 to 20
mA DC signal for transmission. The YTA50 conforms to the
standard DIN form B head mounting.
It is imperative that usres observe the instructions in this
manual to ensure the protection and safety of operators.
