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.
