UC

1. INTRODUCTION

UC508 economy is a Microprocessor based Digital Process Controller, which

can be applied in high-precision measurement and control of temperature, pressure,
discharge, liquid level and humidity etc... A four-digit LCD dual display shows
measured value and set-value for all programming parameters. Instrument
configuration is achieved from the front panel keyboard, without any hardware change.
The user should read this manual thoroughly before using the instrument. It must be
handled with care and should be used accordingly for best results.

2. PRESENTATION



2.1 Features

1. Input signal: Thermocouple, RTD, direct voltage, current programmed from the front panel.
2. Outputs can be set on-off control or PID control with configurable direct/reverse action modes.
3. The input uses digital correction system; there is nonlinear correction form of communal used

thermocouple and resistance thermometer detector.

4. Control output modes hold out relay contact switch, solid-state relay driving voltage, and single-

phase thyristor zero-crossing trigger signal etc.

5. Comprehensive self-detection and protection. In case of error, it provides automatic repair or

prompt message and closes the output.
