<<Contents>> <<Index>> General YTA610Specifications Temperatore TransmitterGS 01C50H01-01EN The YTA610 is the highly accurate temperature transmitter that accepts Thermocouple, RTD, ohms or DC millivolts inputs and converts it to a 4 to 20 mA DC or Fieldbus signal for transmission. The YTA610 supports HART and Foundation Fieldbus communication protocols. HART type is certified as complying with SIL 2 for safety requirement. ■ FEATURES High reliability Dual-compartment housing realizes high resistance capability to harsh environments. Variety of sensor inputs The type of sensor input is user-selectable from thermocouples (T/C), RTDs, ohms, or DC millivolts. Digital communication HART protocol revision is 7 and Foundation Fieldbus. The instrument configuration can be changed by the user with using the Fieldmate or Handheld terminal. Local Parameter Setting Parameter configuration by the push button offers easy and quick setup for parameters. Self-diagnostics function Continuous self-diagnostics capability ensures longterm performance and lower cost of ownership. Dual universal inputs Dual input can accept two thermocouple, RTD, ohm or DC millivolt inputs. Differential or average temperature measurement is selectable. The sensor backup function for automatically switches-over from the primary to the backup upon sensor failure. ■ STANDARD SPECIFICATIONS ■ PERFORMANCE SPECIFICATIONS Accuracy HART communication type: A/D accuracy/span + D/A accuracy (See Table 1 on page 4.)

Table 1. Sensor type, measurement range, and accuracy Note 1: Total Accuracy = (A/D Accuracy / Span + D/A Accuracy) or (± 0.1% of calibrated span), whichever is greater. Accuracy of Fieldbus type: A/D Accuracy. For T/C input, add Cold Junction Compensation Error (± 0.5°C) to the total accuracy. Example: when selecting Pt100 with measurement range of 0 to 400 °C 0.14°C / 400°C*100% of span +0.03% of span = 0.065% of span Since the value is smaller than ±0.1% of span, the total accuracy is ±0.1%.
