AI-9 series high-precision single loop temperature controllerfeature

High precision low-temperature drift measurement technology, using a 24BIT high-resolution A/D converter customized by Yudian, with 50Hz/60Hz interference suppression function, supports extended 32Bit measurement data format, and actual measurement resolution can reach up to 0.001 degrees.

The input can freely select thermocouples, thermistors, voltage, current, and can expand the input and customize non-linear correction tables. The measurement accuracy of Pt100, mV, S, and B type thermocouples (temperature must be greater than 600 ℃) can reach 0.05 level.

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 has advanced and fast self-tuning function of AAT, which can analyze the heating curve and calculate PID parameters when the equipment is powered on and heated up, without the need for back and forth oscillation like traditional AT, 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; You can also choose a 24VDC power supply and have a variety of external dimensions to choose from.

The design concept emphasizes energy conservation and environmental protection, and carefully selects "fever" level energy-saving components. When there is no output or alarm, the overall power consumption of the machine is only about 0.2W, which greatly reduces the temperature rise of the instrument itself and improves 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 the option to 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 is compatible with fixed-point operation mode. When set to 1, only the given value and timing control time need to be set, and it 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.
