UT35A/UT32A Digital Indicating Controllers

GS 05P01D31-01EN

n Overview

The UT35A/UT32A digital indicating 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.

nFeatures

• A 14-segment, active (PV display color changing function) color LCD display is employed.

Two ve-digit, high-resolution displays are possible. Alphabet letters can be displayed in an easy-to-read

manner. The guide display shows parameter names.

• Easy to operate Navigation keys (SET/ENTER and Up/Down/Left/ Right arrow keys) are employed to facilitate making settings.

• 65 mm depth

The small depth enables the mounting in a thin and

small instrumented panel.

• Ladder sequence function is included as standard. This function allows for creating a simple sequence control. Dedicated LL50A Parameter Setting Software (sold separatly) allows for performing programming using a ladder language.

• Various built-in open network functions such as Ethernet are available. Easy connection with various vendors’ PLCs is possible.

• Quick setting function Setting only the minimum necessary parameters for operation is possible.

• Equipped with a multitude of functions Universal I/O are included as standard. PID control,

heating/cooling control, etc. are available.

eter groups

Respectively, four sets of target setpoints, alarm

setpoints, and PID parameters can be set.

The following PID parameter groups can be selected.

• Target setpoint number (SPNO) (The PID number can be set arbitrarily.)

• Measured input zone PID

• Target setpoint zone PID

• Reached target setpoint zone PID

• Tuning results can be selected from two options, Normal or Stable.

• Tuning output limit can be set. (It cannot be used in

heating/cooling control.)
