UT551 Digital Indicating Controller
The UT551 Digital Indicating Controller (1/4 DIN size) is an exceptionally versatile, advanced instrument and comes with 8 powerful control functions. The controller also features an easy-to-see large numeric display. The "SUPER" overshoot suppress function, autotuning, and additionally new "SUPER2" hunting suppress function come as standard functions. Position-proportional control and heating/cooling control models are also available to suit various applications.
- Active Color PV display features:
- Alarm Status: Active color display changes from green (normal) to red (alarm) automatically.
- Deviation Status: Color changes based on a PV deviation from SP.
- User-defined Color: Choose between green or red display for constant readings.
- 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
8 standard control modes, including single-loop control and loop control with dual-PV switching
- 24 V DC Loop Power Supply (24 V LPS) for 2-wire transmitters is available as optional function.
- Expandable inputs and outputs
Expandable up to 8 contact inputs and 8 contact outputs, enabling to set as 8 alarm 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.
- 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.
