Enhancing automation and process connectivity
!
Plug & Play Operation
ETHERNET-based architecture allows new processes to be added as easily. –No need for extensive hardware
to connect and run the application, because all information is managed on the server.
Works with any Modbus TCP/IP compliant software. MODBUS function codes 03,06,08 & 16 are available.
Reduce labor cost in wiring and setup of communications network.
Faster connection speed.

Security Functions with Password
A password can be set to prevent accidental or deliberate
change to the setup parameter settings of the controller.
Applicable models:All the models of GREEN Series (except for UT130,UT150,UT152
and UT155)
Simple Key Operation
Setpoint (SP) can easily be changed: press the or
key to display the required setpoint and then press the
SET/ENT
key to resister it.(See the figure on the right.)
For a programmable controller, display the pattern signal
and press the
RUN
key to start the operation. Press the
RESET
key to stop the operation.
Universal Input
Selectable among TC, RTD, mV and DC voltage.
The type of input signal and input range can be changed at the customer side by some key operation or by using LL100 or LL1100
parameter setting tool.
0.1% Indication Accuracy.
Models UT750, UP750 and US1000 have two universal inputs.
Connectable up to two 2-wire transmitters simultaneously.
All GREEN SERIES instruments have a 15V Loop Power Supply (15V LPS) for a transmitter.
Moreover, 24V LPS is also available simultaneously for some instruments as optional function. Model US1000 has two 24V LPS functions.
Applicable models for 24V LPS: UT321/351, UT450, UT550, UM331/351, US1000
Press the or key

setpoint (SP).
Press the
SET/ENT
key to reg-
ister the setpoint (SP).
Thermocouple Type : K, J, T, B, S, R, N, E, L, U, W, PL-2, PR20-40, W97Re3-W75Re25
RTD Type : Pt100, JPt100
DC Voltage Input : 0.4 to 2V, 1 to 5V, 0 to 2V, 0 to 10V, 0.00 to 1.25V(Note), -10 to 20mV, 0 to 100mV
Note: For universal input 2 of UT420,UT450,UT520,UT550,UT750,UP550,UP750 and US1000 only.

Universal Output
Selectable among Relay, Voltage Pulse and Current outputs.
Relay output: ON/OFF control, Time-proportional PID control
Voltage Pulse output: Time-proportional PID control
Current output: Continuous PID control
Heating/Cooling Control has two sets of universal outputs.
Any combinations with Relay, Pulse and Current outputs are available. There are some limitations to UT320/350 controllers.
Drive the Motorized Control Valve by using Position-Proportional PID.
The position-proportional PID control function has two sets of relay outputs for direct / reverse rotation of motorized control valve.
The side wire input to feed back the valve position is also available.

Deviation Status
Color changes based on a PV deviation from SP
User-defined Color
Choose between Green or Red display for constant readings
The color of display automaticcally switches
from GREEN to RED or RED to GREN.
