Product Description
The UT35A is the advanced model in the UTNext series from Yokogawa Electric Corporation, designed to deliver high-performance PID control for demanding industrial applications.
This 1/4 DIN digital indicating controller features an active color LCD display and integrates both PID control and IEC 61131-3–based sequence control within a single unit. By combining ladder logic and loop control functions, the UT35A reduces reliance on external relays and simplifies panel wiring.
With high-speed processing and universal I/O capability, the UT35A manages complex control strategies with precision and reliability. It is particularly well suited for heat treatment furnaces, food production lines, chemical reactors, and other critical process environments.

-
Local interlocking control
-
Alarm management
-
Multi-step temperature profiles
-
Integrated cascade loops
Typical applications include:
-
Furnace temperature control
-
Pressure regulation systems
-
Liquid level management
-
Process equipment retrofits
Professional FAQ
Does the UT35A support custom ladder logic programming?
Yes. Engineers can configure sequence control using Yokogawa’s LL50G configuration software, allowing custom logical operations and step sequences to be embedded directly into the controller.
Can the display color change based on process conditions?
Yes. The active color LCD can automatically switch (e.g., green to red) during alarm conditions, providing clear visual indication on the plant floor.
Is the UT35A compatible with legacy UT35 mounting dimensions?
Yes. The UT35A maintains the standard 1/4 DIN (96 × 96 mm) panel cutout, making it a practical replacement for earlier UT35 models, although terminal wiring arrangements may differ slightly.
