UT32A Digital Indicating Controller

(Entry model)

GS 05P01F31-01EN

n Overview

The UT32A entry model digital indicating controller is

an easily congurable single-loop controller that can generate relay, voltage pulse, or current signals for control output. The short depth of the controller helps save instrument panel space.

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.

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

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

ON/OFF control, etc. are available.

• LL50A Parameter Setting Software (sold separately)

The parameters of UTAdvanced digital indicating

controller can be built from a PC using this software.

It makes data management even easier.

• Dust-proof and drip-proof

IP66 (for front panel) (Not applicable to side-by-side

close mounting.)

NEMA4 (Hose-down test only)
