The UT150 (1/16 DIN size) are a compact, versatile, general-purpose temperature controllers. These series of indicating controllers use a patented dynamic auto tune and the "SUPER" overshoot suppress function to provide accurate and quick control with minimal over or undershoot . This feature is standard on all UT150 controllers. The heating/cooling control, retransmission output, timer function and communication function are available as optional features.

TModel UT150/Z (valve controllers and valve actuator controllers) have two relay contact outputs to control motorized valves or motorized actuators. Model UT150/Z does not need the valve position feedback signal. This controller estimates the valve position automatically. UT150/Z has MAN mode for moving the valve position manually. Non-linear control function are available to prolong the valve life.

PC-based Setup Parameters & Custom Computation Building Tools

For UT100 Series Controllers
LL100 Light loader computing

The LL100 Parameter Setting Tool is a software package that enables you to set the functional configuration parameters (setup parameters) and operation parameters of a digital indicating controller and a program controller, as well as the program patterns of a program controller, on a PC. The tool lets you the followings:

  • Setting parameters
  • Uploading, downloading and comparing the parameters in the controllers
  • Saving and reading the parameters stored on the storage media
  • Printing out parameters
  • Multi-monitoring

Parameter Setting Display

Simple configuration and parameter help text. In addition to parameter setting, the following functions can be used on this display:

  • Uploading, downloading and comparing the parameters in the controller
  • Saving and reading the parameters stored on the storage media
  • Printing out parameters

Proper management of the setting file minimizes the downtime during maintenance and inspection.

Tuning Display

Trend display of measured values (PV), setting values (SP), and control output values (OUT). Manual tuning is much more efficient when trends of the process can be easily viewed. Auto-tuning and output value setting during manual operation are also possible.

Program Pattern Display

Used to create program patterns. The graphical pattern display allows event settings to be checked at a glance.

Multi-monitoring Function for Centralized Monitoring (up to 16 loops)

  • Easy-to-see trend display- Displays the trends of measured values (PV), setting values (SP), and control output values (OUT).
  • Easy-to-understand panel view- Alarms can be checked at a glance.
  • Automatic recognition for quick connection- Can view up to 16 loops.
  • User-friendly tuning display- PID and operational settings can be changed.
  • Saving in CSV format- Saved data can be readily used in Excel, etc.
