I. Product Overview

The digital display instrument works 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

◆Applicable to standard voltage, current, thermal resistance, thermocouple, and other signal types

◆2-point alarm output, with selectable high-limit alarm or low-limit alarm modes. Alarm sensitivity can be set independently

◆Transmitter output (optional), capable of outputting the measured and converted display value in the form of standard current or voltage for use by other devices

III. Technical Specifications

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

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

Note: The DC power supply should retain a certain power margin. Please configure the power supply according to 24VDC/0.5A per loop, 12VDC/2A. Also pay attention to the power cable length and wire diameter.

◆Operating 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 settings

◆Basic error: less than 0.5%F.S

◆Measurement control cycle: 0.2 seconds

◆Alarm output: 2-point relay output, 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 externally supplying 12V and simultaneously having A1 or A2 model transmitter output function, the transmitter output load capacity 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%

For other specifications, they 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
