Yokogawa UT32A-000-11-00 Digital Indicating Controller

Yokogawa UT32A-000-11-00 Digital Indicating Controller

Product Introduction

The Yokogawa UT32A-000-11-00 belongs to the UTAdvanced series. This digital indicating controller packs many features into a compact 1/8 DIN housing. Its 14-segment active color LCD shows process values clearly. The display changes color to alert operators.

Navigation is simple with five keys: SET/ENTER and four arrow keys. Therefore, you spend less time learning and more time controlling. The UT32A also includes a ladder sequence function as standard. This allows basic logic control without extra hardware.

Multiple communication options are available. However, this base model supports CC-Link and RS485. For Ethernet, choose a different suffix. The controller meets IP66 and NEMA4 ratings for the front panel. As a result, it handles washdown environments well.

Installation and Mounting

The UT32A-000-11-00 has a shallow 65mm depth. This makes it perfect for thin panels.

Mounting steps:
First, cut a 1/8 DIN panel opening (92 x 45 mm). Next, insert the controller from the front. Then, attach the mounting bracket from behind. Finally, tighten the screws evenly.

Do not mount units side-by-side without spacing if you need full IP66 protection. The IP66 rating does not apply to close side-by-side mounting.

Leave enough space for wiring and ventilation. Ambient temperature must stay below 40°C for side-by-side installations.

Frequently Asked Questions (FAQ)

1. Can the UT32A-000-11-00 control both heating and cooling?
Yes, it can. This model supports heating/cooling control. You need to assign the cooling output to an available output point. The deadband is adjustable from -100.0 to 50.0%.

2. Does this controller have Ethernet communication?
No, the UT32A-000-11-00 does not include Ethernet. This base model supports CC-Link and RS485 only. For Ethernet, choose a different suffix code.

3. What is the ladder sequence function used for?
You can create simple logic sequences without a PLC. For example, interlock conditions, timer delays, or basic state machines. Use LL50A software (sold separately) to program it.

4. How do I change the PV display color?
The active color LCD changes automatically based on alarm conditions. You can configure the setpoints for white-to-red switching. This gives a clear visual alert to operators.

5. Is external power needed for a 2-wire transmitter?
No, not if you order the /LP option. That adds a 24V DC loop power supply. It provides 21.6 to 28.0V DC at up to 30 mA. Perfect for powering a 2-wire transmitter directly.
