High precision low-temperature drift measurement technology, using a 24BIT high-resolution A/D converter customized by Yudian, with 50Hz/60Hz interference suppression function and support for expansion
The 32Bit measurement data format has an actual measurement resolution of up to 0.001 degrees.
● The input can freely select thermocouples, thermistors, voltages, currents, and can expand the input and customize non-linear correction tables. Pt100, mV, S, and B type thermocouples have input capabilities
The measurement accuracy of the input type can reach 0.05 level, and Pt100 and mV can be specially customized with 0.02 level accuracy products.
The new AI algorithm can accurately control even large lag systems and has stronger adaptability to PID parameters.
In addition to the classic AT self-tuning function, it also has AAT advanced fast self-tuning function, which can analyze the temperature rise curve and calculate PID parameters when the equipment is powered on and heated up, without the need for
The traditional AT oscillates back and forth, greatly saving equipment debugging time;
The power supply adopts a globally recognized switch mode power supply with a range of 100-240VAC, providing comprehensive power protection function. Even if 380VAC is mistakenly connected for a long time, it will not burn out; also
It can be powered by a 24VDC power supply and has multiple external dimensions to choose from.
● Emphasize the design concept of energy conservation and environmental protection, select "fever" level energy-saving components, and when there is no output or alarm, the overall power consumption of the instrument is only about 0.2W, which causes the temperature rise of the instrument itself
Significantly reduce to improve product reliability and stability.
Adopting advanced modular structure and providing rich output specifications, it can widely meet the needs of various application scenarios, with fast delivery and easy maintenance.
Allow editing operation permissions and on-site parameter tables, and can set passwords to form "customized" instruments.
The communication function supports MODBUS protocol, and multiple network connection methods including TCP can be achieved through the multifunctional communication controller.
Strong anti-interference design, passed 6KV group pulse anti-interference test, anti-interference performance meets the requirements of electromagnetic compatibility (EMC) under harsh industrial conditions.
The digital tube has been upgraded to a new generation of self luminous LED display technology, with no light leakage or viewing angle issues, higher luminous efficiency, more vibrant colors, significantly reduced power consumption, and can
Choose different LED color matching modes.
● Power grid undervoltage instantaneous power-off protection function, with a starting voltage as low as around 50VAC, and a continuous working time of about 1 second after the power grid instantaneous power-off.
When the instrument has multiple sets of input and output, it can provide a comprehensive power supply and optoelectronic isolation solution.
Built in program control function, when the parameter Pno program segment number is set to 0, it can be fully compatible with fixed-point operation mode. When set to 1, only the given value and timing control need to be set
Time can also support up to 50 program control functions.
● Automatic/manual disturbance free switching function.
● It has the function of transmitting measured/given values to 4-20mA or 0-20mA output.
Built in 50 point table/line processing function, which can be used for multi-point correction of measurement value input and high temperature furnace output following measurement value limiting.
The external event input function supports functions such as switching given values, PID parameter switching, and manual/automatic disturbance free switching.
Including multiple alarm mode functions such as upper limit, lower limit, positive deviation, negative deviation, etc., the alarm output position can be freely set.
When the sensor is disconnected, the output percentage can be defined and can be manually set or autonomously restricted by the system.
