UT351-xA Digital Indicating Controller

Model UT351 Digital Indicating Controller is a highly accurate 1/4 DIN controller provided with an Ethernet communication functions. It has a large "Active Color PV Display" for readings with a color changing function, universal input/output and a convenient Auto/Man key to make monitoring easier. In addition, control functions such as auto-tuning, "SUPER" (overshoot suppressing), "SUPER 2" (hunting suppressing), and heating/cooling control are available, and retransmission of variables comes standard. The UT351 is a controller equipped with more advanced functionality and capabilities than were available on previous models. "Ethernet" is a registered trademark of XEROX Corporation.

• An embedded Ethernet communication function is available. Connectivity to host devices is provided by Modbus/TCP protocol.
• The UT351 can use the Ethernet serial gateway function to connect an Ethernet compatible host device with another device using RS485 serial communication function (Modbus/RTU protocol) such as a Green series controller.
• An extra-large digital display allows the indicated values to be read even from a long distance. 20-mm LEDs are used for the process variable display.
• An "Active Color PV Display" color changing function is provided. The PV display color is changed from green to red and vice versa when an alarm occurs or deviation becomes large. The color can also be fixed in green or red.
• Universal input and output enable users to set or change freely the type of measured inputs (thermocouple, RTD, or DCV), measurement range, type of control output (4 to 20 mA current, voltage pulse, or relay contact), etc. from the front panel.
• Parameters can be easily set using a personal computer (requires the model LL100 Parameter setting tool, sold separately).
