YOKOGAWA YTA610 Temperature Transmitter | Dual Sensor, 4-20mA+HART, SIL2, Field Mount

YOKOGAWA YTA610 transmitter specifications. Dual sensor input temperature transmitter, 4-20mA+HART, field mount, SIL2 certified.

Product Overview

The YOKOGAWA YTA610 is a high-performance temperature transmitter from the YTA600 series. It is designed for field-mounting and features dual sensor input capability, accepting either RTD, thermocouple, Ohm, or millivolt signals. The transmitter provides a 4-20mA DC analog output with superimposed HART digital communication. It supports redundant measurement, differential temperature, and average temperature calculations, and is certified for SIL2 functional safety applications.

Important Notes

1. The YTA610 accepts dual sensor inputs and supports HART protocol, but specific options (housing, electrical connection, certification, display) must be selected via the model suffix code.

2. For safety applications, full device assessment and configuration according to the YTA610 Safety Manual is required.

3. HART communication requires minimum loop resistance of 250Ω.

4. For differential measurement, both sensors must be calibrated and configured correctly for accurate ΔT.

5. Redundant mode (backup) ensures process output continues seamlessly if primary sensor fails.

6. The transmitter supports Sensor Bypass Mode (single sensor operation).
