The UT55A and UT52A 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 UT55A/UT52A also support open networks such as Ethernet communication.
UT55A and UT52A Temperature Controller Features
The control mode allows easily configuring settings and making changes with parameters.
For the correspondence between the above control mode and control types for each model, please refer to the specifications of each model.
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.

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.
Alarm action is built by the ladder sequence program inside the UTAdvanced, thus making it possible to reduce costs.
Host System Load is Reduced
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.
* In the case of the UT55A
Select from TC, RTD, mV/DC voltage and DC current.
(DC current input: No shunt resistor required)
The input type and range is user selectable via the front panel or by using the LL50A parameter setting software.
All instruments have a 15 V Loop Power Supply (15 V LPS) for a transmitter. In addition, a 24 V LPS is also available simultaneously for some instruments as optional function.
User selectable for relay, Voltage pulse and current outputs.
Heating/cooling control has two sets of universal outputs.
Drive a motorized control valve by using position-proportional PID.
The following conditions can be set in order to increase the accuracy of calculating PID constants using AT .
The field proven SUPER function utilizes a built-in operator experience and fuzzy theory to deliver fine control and suppress overshoot.
The new SUPER2 function utilizes a built-in operator experience and modern control theory to deliver fine control and suppress hunting.
Parameters that determine controller functions can easily be set: controller model type, controller mode (single-loop control, cascade control, loop control with PV switching, etc.), universal input/output functions, setup parameters and others. It also allows you to create program patterns.
Used to tune a controller's PID parameters. Displays measured input value, target setpoint, and control output value as a trend graph on a personal computer screen, allowing PID parameter modification, AUTO/MAN switching, control output modification in manual operation, etc.
Ladder sequence programs can be created and ladder programs can be monitored.
Can be used to create an electronic device data sheet for Open Network.
Can be set parameters and ladder program while no power supply to controller.
Can be used while attached to the control panel.

* The same operation displays as those of the UT are also available.
Fast-forwarding of program operation
Use this function when checking the program pattern setting. Only times of segments and time events can be faster.
Program pattern-2 retransmission
The controller can serve as a program pattern generator.
Synchronized program operation
If the progress of the operation of one unit is faster, the program operation can be forcibly stopped by digital input when switching between segments. Thus, synchronized program operation can be performed.
The controller menus and layout are adjusted in accordance with the level (EASY, STD, PRO) of information required by the user. If simple temperature or level control is needed, then select the easy configuration. Very sophisticated applications are no problem for the UTAdvanced. Just select the PRO setting and make use of the additional functionality shown in this mode. Advanced applications can be programmed in the PRO setting and then changed back to the easy setting to lock out functions not required by operators.
With Yokogawa's Active color display you can instantly tell, at a glance, the status of your process.
Alarm Status: Active color display changes from white (normal) to red (alarm).
Deviation Status: Color changes based on a PV deviation from SP.
User-defined Color: Choose between white or red display for constant Readings.
The 65-mm depth of the controller reduces the constraints on installation location.
The navigation keys is an intuitive method to navigate the controller's configuration menus and setting its various menus. Navigation arrows even tell you what button to push next.
It is easy to assign frequently used functions, such as the operation mode switch, Run/Stop, program pattern selection, Remote/Local, alarm latch release, and PID parameter display. The function of an external switch can also be assigned to the front panel key in conjunction with a ladder sequence program.
The UTAdvanced is equipped with a scrolling text feature that fully lists the parameter being modified. There is no guessing what parameter you are looking at. It is possible to turn off scrolling the text function.
The UTAdvanced is fluent in multiple languages — English, Spanish, French, and German. The use of the UTAdvanced by local language operators is not an obstacle.
Parameter values (SP, P, I, D, ALM1, etc.) configured by the user can be stored in the controller as the default values. Even if a parameter set value is accidentally changed, it can be restored to the original value with a simple operation.
Now you can choose a color that matches your work area: white (light gray), or black (light charcoal gray).
LL50A Parameter Setting Software (sold separately) allows for easily setting parameters.
Using the message function and turning the contact input on/off, the message registered beforehand can be displayed on PV display by interrupt.The message is registered using LL50A Parameter Setting Software.The messages are limited to 20 alphanumeric characters. A maximum of four messages can be registered.
Minimum parameters necessary for operation can be set.
The password function can prevent inadvertent changes to the parameter settings. If a password is set, the password is required when moving to the Setup Parameter Setting Display. When the password is verified, can be changed to the Setup Parameter Setting Display.
A simple and easy network connection is provided!
A built-in function in the controller eliminates the need for a converter and makes wiring simple.
Modbus TCP/IP, a protocol that allows the controller to connect to any Ethernet network and have the ability to exchange data with the computers or devices on that network.
The data of UTAdvanced (slave units) can be displayed and saved on the DXAdvanced using
the Modbus RTU function.
Embedded open networks will provide direct connection to PLC's.
The use of the ladder sequence program makes it possible to exchange analog data and status data between communication-capable UTAdvanced.
Example: A UTAdvanced in which an input error occurs sends a signal to another UTAdvanced to enable that UTAdvanced switch to MAN operation, thus shifting the whole system into a safe mode. In such a case, the safety mechanism can be built into the UTAdvanced and is not required in the host system.
In coordinated operation, a single UTAdvanced termperature controller is used as a master controller and multiple UTAdvanced or other UTAdvanced digital indicating controllers as slave controllers.
The slave controllers are operated in accordance with the actions of the master controller.
A protocol used for communicating with a general-purpose personal computer, or UTAdvanced series link module and serial communication module of FA-M3R (range-free controller).
Backed by the high reliability and quality that Yokogawa has cultivated over many years.
UTAdvanced is environmentally safe when disposing.
UTAdvanced can also be used for food-processing equipment with washable control panels.
