YOKOGAWA UT750 Digital Indicating Controller (with Custom Computation)

The UT750 Digital Indicating Controller (1/4 DIN size) is an exceptionally advanced instrument with high control capabilities and comes with 13 powerful control functions, along with customized computing functions. The controller also features an easy-to-see large numeric display, as well as an LCD display for setting parameters interactively. The "SUPER" overshoot suppress function, autoruning, and additionally new "SUPER2" hunting suppress function come as standard functions.

• Fast and accurate
  Tracks fast-changing signals at ±0.1% accuracy and at up to 50ms input sampling period.
• Sharp and Large 5-digits LED display with 11 x 20 mm digits
• Easy control mode selection
  13 standard UT control modes, including single-loop, cascade, and dual-loop control.
• Standard, seven contact inputs and seven contact outputs
• Support for Light Loader - LL100 PC-based Parameter Setting Tool
  Easy parameter setting on a PC screen, enabling data to be transmitted through the front panel using an optical communication adapter.
• Customized computing, including the four arithmetic operations, as well as logical, pressure compensation and switched-PV computations functions (LL200 PC-based Custom Computation Building Tool is required separately)
• Easy to understand hardcopy format and handy CD-ROM user's manuals.
• New communication method Modbus, PC-Link & Ladder protocols and coordinated operation are supported.

■ Main Features

• Extra-large digital display allows the indicated values to be read even from a long distance.  LEDs of 20 mm height are used for the process variable display.  This is a five-digit display for higher resolution.

• User-friendly full dot LCD display. Not only the target setpoint and other control related parameters but also a deviation trend record or a deviation analogue bar can be  displayed.

• Thirteen types of control function, including single-loop control, cascade control, loop control with PV auto- selector, and custom computation control, enabling the operator to start control operation immediately after simply entering the settings.

• Custom Computation function, which allows users’ own configuration for signals, enable them to realize such functions as complicated computation for input compensation or sequence logic.  ( “Custom Computation Building Tool <model name: LL200>  is necessary to use this function.)

• Universal input and output enable users to set or change freely the type of measured inputs (thermocouple, RTD, or DCV), measurement input range, type of control output (4 to 20mA current, voltage pulse, or relay contact), etc. from the front panel.

• Equipped with seven contact inputs and outputs each, which are further expandable up to 23 inputs and outputs each by adding contact I/O signal expansion modules.

• Various communication function are provided. Communication is possible with personal computer, programable logic controller, and other controllers.

■ Model and Suffix codes

Note: Using an optional custom computation building tool (Model LL200-E10) that runs on a personal computer, you can build a variety of computation (eg., four arithmetic operations, logical operations, ten-segment linearizer computations, temperature compensation factor computations, and pressure compensation factor computations) to be applied to the controller’s I/O signals.

Standard accessories: Brackets (mounting hardware), unit label, User’s Manuals, and User’s Manual (reference) (CD- ROM version). Specify suffix code according to the designated UT mode.

Digital I/O expansion module

Note : Digital I/O expansion modules do not have CE/UL marking.
