UT55A, UT52A Digital Indicating Controller

(Panel Mounting Type)

GS 05P01C31-01EN

n Overview

The UT55A and UT52A 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 UT55A and UT52A also support open networks such as Ethernet communication.

The UT55A and UT52A have a DIN rail mounting type (with option code /MDL). For more details, please see

General Specication GS 05P01C81-01EN.

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.

(UT52A support CC-Link and RS485 communication only.)

• Quick setting function Setting only the minimum necessary parameters for operation is possible. (For single-loop control only)

• Equipped with a multitude of functions Universal I/O, eight control modes (cascade control, etc), and retransmission output are included as standard. PID control, heating/cooling control, feed

forward control, etc. are available.

• LL50A Parameter Setting Software (sold separately) The parameters and ladder programs 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.)

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

(c) Auto-tuning

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