The UT35A and UT32A temperature controllers employ an easy-to-read, 14-segment large color LCD display, along with navigation keys, thus greatly increasing the monitoring and operating capabilities. A ladder sequence function is included as standard. The short depth of the controller helps save instrument panel space. The UT35A/UT32A also support open networks such as Ethernet communication.
- 4 target setpoints (PID numbers) available as standard
- 3 alarm independent common terminals available as standard
- Ladder sequence programs can be built
- Simple operation
- Up to 8 DOs (combinations available)
- Multiple language operation manual (Japanese, English, German, French, Spanish, Chinese and Korean) available. Please specify the desired language when ordering.
- Detailed code model available to customize specifications best suited to you.

Advanced Control
Control Modes
The control mode allows easily configuring settings and making changes with parameters.
- Single-loop control
-
5 Built-in Control Types
- PID control
- ON/OFF control (1 point of hysteresis)
- ON/OFF control (2 points of hysteresis)
- Two-position, two-level control
- Heating/cooling control
For the correspondence between the above control mode and control types for each model, please refer to the specifications.
Ladder Sequence Control
With built-in ladder sequence control, the range of applications are dramatically increased. This feature is standard in all the UTAdvanced controllers (except UM33A). The ladder sequence control function can replace a small PLC required by the application. Sequence control and PID control can be performed simultaneously.
- Monitoring and control of external machinery
E.g.: Lamps, switches, timers - Solve digital input/output logic functionality easily.
Number of basic command types: 13

Application Examples of Ladder Sequence Program
Alarm Sequence Control Circuits Can be Reduced
The ladder sequence program is built in the UTAdvanced as standard. The ladder sequence function enables monitoring and controlling peripheral devices such as relays, thus making it possible to reduce costs.
[Conventional]
Alarm action was built by a sequence control circuit (relay, timer, etc.) outside of the controller. |  | [UTAdvanced]
Alarm action is built by the ladder sequence program inside the UTAdvanced, thus making it possible to reduce costs. |
Host System Load is Reduced
[Conventional]
Various types of analog data were captured into the host system (PLC, etc.) and calculated, and the results were processed by the field controller for control via a command. | [UTAdvanced]
The UTAdvanced with up to 4 analog inputs* enables various types of analog data to be captured directly into the controller and calculated by the ladder program, thus reducing the system-building load of the host. Action: Various types of analog data were captured into the host system (PLC, etc.) and calculated, and the results were processed by the field controller for control via a command.
