UT750 Digital Indicating Controller
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, autotuning, 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
Expandable up to 23 inputs and 23 outputs by connecting I/O expansion modules
- 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.
