YASAWA DI-01 Digital Indicator Controller

Product Overview

A digital indicator controller is a device that can convert analog or digital signals into digital form for display and control related parameters. It usually consists of a digital display screen, input signal interface, signal processing circuit, control circuit, etc. It can be used in conjunction with various sensors and is widely used in industrial control, measurement and other fields.

Specifications

Measurement accuracy: usually 0.2% FS ± 1 word or 0.5% FS ± 1 word.

Resolution: ± 1 word.

Display mode: Dual high brightness LED digital display, capable of displaying measured values, set values, external given values, etc., with a display range of -1999~9999.

Control output: There is PID current/voltage control output, such as 0-10mA (load resistance ≤ 750 Ω), 4-20mA (load resistance ≤ 500 Ω), etc; There are also PID forward/reverse valve position control outputs, such as relay control outputs (AC220V/3A, DC24V/5A, resistive loads), etc.

Communication output: Standard serial bidirectional communication interfaces, such as RS-485, RS-232C, etc., with a baud rate of 1200-9600bps that can be set, using the standard MODBUS RTU communication protocol.

Working power supply: Supports various power supplies such as AC220V ± 10% (50Hz ± 2Hz, linear power supply), AC90~265V (switching power supply), DC24V ± 2V (switching power supply), etc.

Performance Characteristics

High precision measurement: With high measurement accuracy and resolution, it can accurately display the numerical values of physical quantities.

Multiple output modes: Provides rich control and communication output modes to meet the connection and control needs of different devices.

Clear Display: Dual high brightness LED digital display, combined with dual light column display, provides clear and intuitive data display.

Alarm function: Multiple alarm modes can be set, such as relay upper and lower limit alarm output, with an alarm accuracy of ± 1 word, which can promptly remind abnormal situations.

Convenient parameter setting: numerical settings can be made through touch sensitive buttons on the panel, and the parameter settings can be password locked and permanently saved after power failure.

working principle

The digital indicator controller receives input signals from external sensors. If it is an analog signal, it is converted into a digital signal through an internal analog-to-digital converter (ADC), and then processed through filtering, amplification, calibration, etc. to eliminate noise and errors. The processed digital signal is transmitted to the display unit for display, and can be controlled for output according to the set parameters. It can be linked with other control systems to achieve monitoring and control of physical quantities.

Precautions

Installation environment: It should be installed in a place with an ambient temperature of 0-50 ℃, relative humidity ≤ 85% RH, and avoid strong corrosive gases.

Wiring operation: When wiring, the power supply should be disconnected first to ensure safety and avoid operations such as wiring, inspection, and component replacement while powered on.

Electrostatic protection: The electronic components inside the equipment are sensitive to static electricity, and anti-static measures should be taken during operation to prevent damage to the circuit board.

Parameter setting: Non professionals are not allowed to modify internal parameters arbitrarily to avoid affecting the normal operation of the equipment.

Application scenarios

Industrial process control: used in industries such as chemical, power, and petroleum to monitor and display key parameters such as temperature, pressure, and flow in real-time.

Mechanical equipment monitoring: In the field of mechanical manufacturing, the speed, displacement, and other numerical values of mechanical equipment can be monitored to ensure process stability and accuracy.

Experimental testing: Used in various testing instruments in the laboratory to facilitate quick reading and recording of experimental data by experimenters.

Measurement and weighing: In the logistics and warehousing industry, it is used for digital scales, flow meters and other equipment to achieve automatic measurement and statistics.
