1. INTRODUCTION

UI series of universal process indicator is a high performance indicator that can

be used to monitor wide range of input signal. The various input signals could easily
be selected from the front keypad without any change in Hardware. The Standard
model comes with 2-alarms, 24V auxiliary power supply for transmitter and analogue
retransmission 4 ~ 20 mA DC output. The unit features double display for indication of
process value and programming data. The large and bright PV display, robustness of
product makes the product suitable for industrial applications. The retransmission
output could be taken to PLC, recorder and other applications, for other functions. RS-
485 or RS-232 communication is also optionally available.

Applications

The instrument can measure and display any range of Current, Voltage and temperature

through RTD-Pt 100 signal input. The user can select data hold or high PV hold. The instrument can be
used with 2-wire Differential Pressure Transmitter, Pressure Transmitter, Temperature Transmitter,
Temperature Sensor or any other industrial process parameters (for non-linear input). RS485
communication is also optionally available. The input, output and the power supply are isolated.
