Enhancement
nOverview
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 Specification GS 05P01C81-01EN.
nFeatures
•A 14-segment, active (PV display color changing function) color LCD display is employed.
Two five-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.)
NEMA4 (Hose-down test only)

•Applicable standards: JIS, IEC and DIN (ITS-90) for thermocouples and resistance-temperature detectors (RTD)
•Input sampling period: Synchronized to control period
•Burnout detection
Upscale and downscale of function, and OFF can be specified for the standard signal of thermocouple and resistance-temperature detector (RTD).
For integrated signal input, 0.1 V or 0.4 mA or less is judged as a burnout.
•Input bias current: 0.05 μA (for thermocouple and resistance-temperature detector (RTD))
•Resistance-temperature detector (RTD) measured current: About 0.16 mA
•Input resistance
1 MΩ or more for thermocouple/mV input About 1 MΩ for voltage input
About 250 Ω for current input (with built-in shunt resistance)
• Allowable signal source resistance
250 Ω or less for thermocouple/mV input
Effect of signal source resistance: 0.1 μV/Ω or less 2 kΩ or less for DC voltage input
Effect of signal source resistance: about 0.01%/100 Ω
• Allowable wiring resistance
Up to 150 Ω per line for resistance-temperature detector (RTD) input (conductor resistance between the three lines shall be equal)
Effect of wiring resistance: ±0.1°C/10 Ω
• Allowable input voltage/current
±10 V DC for thermocouple/mV/mA or resistancetemperature detector (RTD) input
±20 V DC for V input ±40 mA DC for mA input
• Noise reduction ratio
40 dB or more (at 50/60 Hz) in normal mode 120 dB or more (at 50/60 Hz) in common mode
• Reference junction compensation error ±1.0°C (15 to 35°C)
±1.5°C (-10 to 5°C and 35 to 50°C)
Auxiliary Analog Input Specifications
•This function can be used for remote setpoint setting, external compensating input, auxiliary input for computation, etc.
•Number of input points: see the model code table.
