AI-8 series high-performance single loop temperature controllerMain features

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 input can freely select thermocouples, thermistors, voltage, current, and can expand the input and customize non-linear correction tables. Some input types have measurement accuracy up to 0.05 level.

High precision low-temperature drift measurement technology, using a 22/24BIT high-resolution A/D converter customized by Yudian, and equipped with 50Hz/60Hz interference suppression function.

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.

Supports multiple communication protocols, including the AIBUS protocol independently developed by Yudian, which is concise and efficient, and the universal MODBUS protocol; Multiple network connection methods, including TCP, can be achieved through a 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.

The design has a wide temperature range of -10~+60 degrees and uses high-precision crystal oscillators. The actual aging test temperature can reach up to 100 degrees.

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. The AI-8 * 8 series can support up to 50 program control functions.

● Automatic/manual disturbance free switching function, can be set as a handheld device for use.

● Equipped with external setpoint control function (only for AI-8 * 8 series) and measurement/setpoint conversion to 4-20mA or 0-20mA output function.

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.

Multiple options for thermocouple cold junction compensation: In addition to the regular internal compensation mode, it supports high-precision external CU50 and freezing point compensation methods.

When the sensor is disconnected, the output percentage can be defined and can be manually set or autonomously restricted by the system.

Multiple disk and rail installation methods are available: including 48 * 48, 72 * 72, 48 * 96, 96 * 48, 96 * 96, 160 * 80, 80 * 160 disk installation forms and D7 rail installation modules
