YOKOGAWA YTA610‐JA1A4DDKU2 YTA610 Series Temperature Transmitter

YOKOGAWA YTA610‐JA1A4DDKU2 YTA610 Series Temperature Transmitter

The YTA610 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 20 mA DC analog signal or Fieldbus digital signal. HART 7 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.

YTA610 features include:

Dual-compartment field-mount housing

Choice of HART 7, or FOUNDATION™ Fieldbus ITK 6 Protocol

Local Parameter Setting function (Indicator model)

Basic diagnosis
