Product Description

The Yokogawa  UT35A  is a high-performance, general-purpose digital indicating controller from the UTAdvanced series, designed for precise  single-loop control of temperature, pressure, flow, and other process variables. Featuring a standard ladder sequence  function (equivalent to a mini-PLC), it combines powerful control capabilities with exceptional ease-of-use, making it  ideal for a wide range of industrial automation applications.

Product Features

• High-precision digital indicating controller with universal input for temperature, pressure, flow and other      process variables.

• Advanced PID control with auto-tuning, supporting heating/cooling control and ON/OFF control.

• Built-in 300-step ladder sequence logic, enabling simple PLC-like interlock and sequence control.

• Bright color LCD display with PV status indication for clear and intuitive operation.

• Multiple communication options including Ethernet (Modbus TCP), RS-485 (Modbus RTU) and optional CC-Link,      PROFIBUS-DP.

• Compact 1/4 DIN size with short body depth for easy panel installation.

• IP66 (NEMA4) front panel for dust and water resistance in harsh industrial environments.

• Wide power supply range: 100–240 V AC, suitable for global applications.

• Supports multiple languages and easy parameter setup for improved usability.

• High reliability and long service life, backed by Yokogawa’s industrial quality standards.

Core Functionality

1.Control performance:

• Control mode: Built in 8 control types, including PID control, ON/OFF control, heating/cooling control,      feedforward control, etc., supporting single loop, cascade, and backup loop control;

• Response speed: The control cycle is fixed at 200ms, and the number of steps supports 300 step ladder diagram      programming. Although it is simplified compared to UT55A, it is sufficient to meet the single loop control needs      of most manufacturing devices;

• Accuracy: The indicated accuracy is as high as ±0.1%, suitable for high-precision control scenarios;

2.Display and Operation:

• It is equipped with a large 14-segment color LCD display and navigation keys, which significantly improves      monitoring and operational performance.;

• Supports a multilingual interface, including English, German, French, Spanish, Chinese, Korean, etc., which must      be specified when ordering;

3.Communication and Integration

• It supports various open network communication protocols such as Ethernet (Modbus/TCP), RS-485 (Modbus/RTU), and      PROFIBUS-DP, enabling easy integration with PLC or DCS systems;

• Some models support the serial port gateway function, facilitating the upgrade of legacy systems;
