Yokogawa UT35A/UT32A Digital Indicating Controller: Features And Specifications.pdf

## Yokogawa UT35A/UT32A Digital Indicating Controller Summary

The Yokogawa UT35A and UT32A are compact, powerful digital indicating controllers designed for industrial automation applications. They offer:

Key Features:

High-Resolution Color LCD Display: 14-segment active color display with two five-digit resolutions, easily readable alphabet letters, and guide displays for parameter names.
Intuitive Navigation: Easy-to-use navigation keys (SET/ENTER and arrow keys) simplify setting adjustments.
Compact Design: 65mm depth allows for mounting in thin instrument panels.
Built-in Ladder Sequence Function: Create simple sequence controls using a dedicated software tool (LL50A Parameter Setting Software).
Open Network Compatibility: Support for Ethernet, CC-Link, and RS485 communication (UT32A only).
Versatile I/O Options: Universal I/O with analog inputs/outputs, contact inputs/outputs, and retransmission outputs included as standard.
Robustness: Dust-proof and drip-proof design (IP66 for front panel; NEMA4 for hose-down test).

Control Capabilities:

PID Control: Supports PID control with auto-tuning capabilities.
Multiple Control Modes: Single-loop control, ON/OFF control, two-position two-level control, and heating/cooling control.
Advanced Functions: "Super" function for overshoot suppression, "Super 2" function for hunting suppression, STOP preset output, input ERROR preset output, MANUAL preset output, tight shut function, and rate-of-change limiter.
Alarm Management: Various alarm types (measured value, deviation, rate-of-change, etc.) with customizable actions and delays.
Contact I/O Flexibility: Assigns input error conditions, operation conditions, alarms, or other conditions to contact inputs and outputs.
Ladder Sequence Control: Supports up to 7 digital input points and 8 digital output points for complex control sequences.

Model Differences:

UT35A: More advanced features, higher I/O capacity (up to 7 digital inputs and 8 digital outputs).
* UT32A: Limited I/O options compared to UT35A (up to 4 digital inputs and 5 digital outputs), but still suitable for many applications.
