UT321 Digital Indicating Controller
The UT321 Digital Indicating Controller (1/8 DIN size) is a compact, economical, general-purpose instrument that comes with Active Color PV Display function, which changes LED color of large display between Green-color and Red-color automatically based on a PV deviation or Alarm status. The UT321 controller is functionally equivalent to the UT351 controller, but smaller in width. The unit has a AUTO/MAN switching key, and optional heating/cooling control, autotuning, PID control functions with the "SUPER" overshoot suppress function and additionally new "SUPER2" hunting suppress function. The retransmission output and the sensor power supply (15 V DC) are standard. The UT321 controller offers the same functions and power as higher-grade models.
- 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.
- Small, space-saving
Slim body 48 (W) x 96 (H) x 100 (D) (mm)
- Standard retransmission output (also usable as 15 V DC loop power supply terminals).
- Optional heating/cooling control
- Optional heater burnout alarm
- Optional 24 V DC Loop Power Supply (24 V LPS) for 2-wire transmitters.
- 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
