The YTA710 provides high accuracy, stability, and reliability. 

The housing structure adopts reliable dual-compartment structure.

The sensor input can be choice of single or dual inputs. This input

can accept the RTD, thermocouple, ohm, or DC millivolt. It converts

the sensor input to a 4 to 20mA DC analog signal or Fieldbus digital signal.

HART 7 Protocol, BRAIN Protocol or FOUNDATION™ Fieldbus ITK 6 version

are available. The dual input can accept two sensors calculation of the

differential or average value and the sensor backup function.

Sensor backup functions for automatically switches-over from the primary

to the backup upon sensor failure. By adoption of local parameter switch

on the Indicator, it becomes easy to do the on-site setting work.
