Product Description
The UT55A-040-11-00/LP is a 1/4 DIN digital indicating controller belonging to the Yokogawa UTAdvanced Series. It is designed for high-precision PID control in thermal and process automation applications.
The unit features a 14-segment color LCD display for clear visualization of Process Variable (PV), Setpoint (SP), and Output (OUT) values in real time. This improves operator situational awareness in industrial control environments.
The controller supports advanced control functionality, including proprietary Ladder Control, which enables simple sequence logic operations alongside standard PID control. This allows the controller to replace small PLC logic in basic interlocking or timing control applications.
The /LP suffix indicates integrated 24V DC loop power supply capability, allowing direct power excitation for two-wire field transmitters without requiring an external power supply. This is especially useful in remote monitoring installations.

FAQ
Q1: What does Ladder Control do?
It allows the controller to perform simple logic operations such as heater interlocks or timed process sequencing without requiring a PLC.
Q2: Can the input type be changed?
Yes. The UT55A is a universal input controller, and input type configuration can be changed via the front panel or LL50A configuration software.
Q3: Does it support multi-color alarm indication?
Yes. The PV display color can automatically change (e.g., green to red) when alarm thresholds are triggered.
