Based on the new generation of modular and platform technologies, with highly integrated functions, it has been widely applied in industries such as semiconductors and new energy.

Functional Features

This product is a high-performance instrument with dual input and cascade control function; Measurement accuracy of 0.2~0.05 level, with a free warranty period of 5-10 years.

● It has dual input signals with the same hardware, eliminating the external input specifications of 5V and valve signal feedback input lines.

Dual input can be used as the main control and auxiliary control inputs to form a cascade control loop internally, achieving complex cascade regulation functions. It is suitable for situations with large lag or disturbances that require suppression of overshoot and precise control.

It can automatically analyze the temperature difference between the main control and the auxiliary control and correct the cascade control algorithm, making the previous complex cascade control debugging process as convenient as ordinary single loop PID control.

If cascade regulation is not used, dual input can also form a dual thermocouple hot backup, which automatically switches to the backup thermocouple as input when the main thermocouple is open circuited; Or choose the high or low value of dual input as the main control input.

Yudian's new AI artificial intelligence control algorithm supports multiple input specifications and module expansion of input and output functions; Can provide SSR, linear current, and thyristor triggering functions.

● Support AIBUS and MODBUS compatible communication protocols independently developed by Yudian; Multiple network connection methods such as TCP can be achieved through communication protocol controllers; 10mS fast communication response; Unlimited parameter write times; Allow customers to customize the continuous arrangement of 8 commonly read and write parameters for MODBUS communication, making it easy for the MODBUS protocol to read commonly used parameters with just one instruction, thereby improving communication efficiency and performance.

Advanced platform modular design structure allows customers to choose from various forms of external size panels and display operation interfaces, including multi size disk mounted digital display instruments, DIN rail mounted types, and TFT true color touch screens with curve memory and programmable flowcharts; Allow customers to freely choose and install multiple types of input/output modules; Allow customers to edit operation permissions and on-site parameter tables, and set passwords to create "customized" instruments.

The design has a wide temperature range of -10~+60 degrees, and the actual aging test temperature for PCB motherboards (excluding shells) can reach up to 100 degrees.

Ultra low self energy consumption, instrument power consumption is only about 0.2-0.3W when there is no output.

Anti lightning power protection, long-term misconnection of 380VAC power supply will not damage the instrument.

When the instrument has multiple sets of input and output, it can provide a comprehensive power supply and optoelectronic isolation solution.

Built in 0-50 segment program control function, and fully compatible with fixed-point operation mode.

The heating and cooling rate limiting function can be combined with fixed-point control or program control.

● Automatic/manual disturbance free switching function, can be used as a handheld device; Heating and cooling dual output function.

● It has the function of external setpoint control and the function of converting measured/setpoint values into linear current 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 switching between given values and manual/automatic undisturbed switching.

● Multiple alarm mode functions, and the alarm output position can be freely set.

In addition to internal compensation, the thermocouple cold end also supports high-precision external CU50 and freezing point compensation methods.

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

● Multiple external dimensions available in both disc and rail types.
