YTA710 Temperature Transmitter

YTA710 Temperature Transmitter

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.

YTA Total Insight offers valuable information throughout the devices’ lifecycle. Simple lineup and a wide range of international approvals help the customer select the right product. Various ways of configuring devices contribute to reduced installation and configuration time. Valuable diagnostic information leads to improved process efficiency. Providing timely maintenance information contributes to reduced maintenance cost. The YTA710 enables advanced linearization of 20 types of industrial temperature sensors and input signals. The A/D accuracy of the representative Pt100 sensor is 0.1°C. Analog D/A accuracy of the output is 0.02%.

Accuracy & Stability

Very good accuracy: for Pt100 (RTD) input, ± 0.10 °C.

Stable performance and reliability for long-term field use.

Robust / Rugged Housing

Dual-compartment field-mount housing: field-wiring terminals separated from electronics for better protection against moisture, vibration, etc.

Housing materials: aluminum or stainless steel options.

Universal Sensor Inputs

Supports a variety of sensor types: RTDs, thermocouples (T/C), ohms (resistance), and DC millivolt signals.

Can be configured for single or dual sensor input.

Dual sensor input modes: backup (if one fails), averaging, or differential measurement.

Communication / Output Protocols

Analog output: 4–20 mA.

Digital protocol options: HART 7, BRAIN, FOUNDATION™ Fieldbus (ITK 6).

Local Configuration / Parameter Setting

Models with an indicator have a Local Parameter Setting (LPS) function: you can set parameters via push-buttons on the device itself.

Advanced Diagnostics

Built-in diagnostics for sensor health, signal integrity, etc.

Designed to support safety-critical applications (SIL). YTA710 is certified to IEC 61508.

Sensor Matching

Uses sensor matching for RTDs: can apply Callendar–Van Dusen coefficients to correct for the real RTD curve vs the standard curve, improving measurement accuracy.

Supports IEC 60751 standard for RTD resistance vs temperature.

Safety / Functional Safety (SIL)

Certified for SIL 2 in single-channel configurations; SIL 3 possible in dual-transmitter setups.

Comes with FMEDA data (safety analysis) from Exida.

Optional detachable lightning protector: can be installed on the terminal block.

Global Certifications

Wide certification / approvals: FM, CSA, ATEX, IECEx, INMETRO, etc.

Intrinsically safe versions available (e.g., Ku2 version).

Temperature Range & Power / Supply Conditions

Operating ambient temperature is wide (depends on model), e.g., –40 °C in some configurations.

Insulation / dielectric strength designed to handle field conditions (e.g., 500 V RMS dielectric strength).

Configuration Tools

Can be configured / parameterized via Yokogawa FieldMate or a HART handheld terminal.

Local parameter changes possible through the LPS interface (if the device has an indicator).
