I. Product Introduction

The digital display instrument is used together with various sensors and transmitters with analog output to complete the measurement, conversion, display and control of physical quantities such as temperature, pressure, liquid level and composition

II. Functional Features

◆Error is less than 0.5%F.S, and it is equipped with calibration and digital filtering functions

◆Suitable for standard voltage, current, thermal resistance, thermocouple and other signal types

◆2 alarm outputs, with selectable high-limit alarm or low-limit alarm mode. Alarm sensitivity can be set independently

◆Transmitter output (optional), which can output the measured and converted display value in the form of standard current and voltage for use by other equipment

III. Technical Specifications

◆Power    Supply: 85V AC~265V AC, 100VDC~380VDC, power consumption less than 6W

               10VDC~36VDC, power consumption less than 6W

Note: A certain power margin should be reserved for the DC power supply. Please configure the power supply according to 24VDC/0.5A, 12VDC/2A for each unit. And pay attention to the length and wire diameter of the power cable.

◆Working environment: 0℃~50℃, humidity below 90%R.H, non-condensing.

◆Display range: -1999~9999, decimal point position can be set

◆Input signal type: universal input, selectable through parameter setting

◆Basic error: less than 0.5%F.S

◆Measurement control cycle: 0.2 seconds

◆Alarm output: 2 relay outputs, contact capacity 220V AC, 3A

◆Transmitter output:

Photoelectric isolation, output resolution 1/3000, error less than ±0.2% F.S

DC current or DC voltage output must be specified when ordering, load capacity greater than 600Ω.

For DC current output, 4mA~20mA, 0mA~10mA, 0mA~20mA can be selected through settings; for DC voltage output, 1V~5V, 0V~5V can be selected through settings.

0V~10V transmitter output must be specified when ordering

Transmitter output is an optional function and must be specified when ordering, otherwise the instrument does not have this function.

When the external 12V supply also has the A1 or A2 model transmitter output function, the load capacity of the transmitter output is 450Ω

◆External power supply

Used to supply power to the transmitter, the error between the output value and the nominal value is less than ±5%

Other specifications must be specified when ordering

The external power supply of the instrument can only be used together with the sensors or transmitters connected to the instrument
