Yokogawa UT32A-000-11-00 | 14-Segment Color LCD Ladder Sequence Controller

Oiltech Controls’s Insight

• The UT32A-000-11-00 is a high-density 1/8 DIN controller designed for space-critical control panels.
• Engineers benefit from the built-in ladder sequence function, allowing logic control without an external PLC.
• The 14-segment “Active Color” LCD provides immediate visual feedback, turning from white to red during process deviations.
• Universal I/O and 50ms sampling resolution make it a versatile choice for high-speed thermal and pressure loops.
