AI-82XX series economical multi circuit temperature controllerIntroduction

It is a multifunctional 4-circuit regulator with the ability to externally expand multiple input and output modules. By adding external expansion modules, AI-8246G can achieve up to 96 measurement and control functions, meeting the needs of various emerging industries for small volume and multi loop control. In the extended mode, the upper computer only needs to communicate with one instrument to control up to 96 measurement and control circuits, which can greatly improve communication efficiency compared to the mode that requires accessing multiple address instruments.

AI-82XX series economical multi circuit temperature controllerFeatures:

2. Provide a variety of input types and circuit quantities for customers to choose from;

3. 24 bit high-performance A/D converter sampling, measured using inspection method, high cost-effectiveness;

4. Optional NPN, PNP, and SSR driver outputs or linear voltage/current outputs; Optional 2-channel alarm output;

5. Supports Modbus communication protocol, with a baud rate range of 1200~115200.

Advantages:

High reliability and low energy consumption design, group pulse anti-interference passed 8KV testing; High temperature passed the aging test at 100 ℃ Celsius; The typical power consumption of the instrument itself is less than 0.3W without output conditions.

A brand new multi-channel operation interface with built-in LED digital display, which can quickly view and modify any channel parameter setting value, edit all register values inside the instrument, and work in emergency even if the upper computer fails.

When selecting different numbers and functions of control circuits, their usage and register addresses are consistent, which means that customers only need to learn to use the AI-8246G single model instrument to meet various functional requirements, greatly reducing learning costs.

An operational mode that combines high degree of freedom and efficiency. All functions of AI-8246G can be implemented through reading and writing register parameters. Its registers are divided into channel parameters, input-output group parameters, and common parameters. Channel parameters are independently set parameters for each channel, with 12 parameters per channel, including setpoint, PID parameters, and alarm parameters; There are four different sets of configuration parameters for input and output, which can be selected and called by each input and output channel respectively; Public parameters are globally used parameters, such as baud rate and communication address. Based on the parameter group definition mode, AI-8246G can greatly reduce the overall number of registers while retaining flexibility and powerful functionality, thereby simplifying the operation mode and improving the read and write efficiency of the upper computer. For example, if the four input circuits of AI-8246G have a unified specification, the first set of parameters can be selected for all input parameters. This way, only one set of input configuration parameters needs to be set to define the input specifications of all circuits. You can also choose different parameter groups to define different input specification types. One AI-8246G can define up to 4 different types of input specifications, which is sufficient to meet the vast majority of application scenarios.

The AI-8246G has almost no limit on the number of external input and output modules that can be expanded, and can be quickly customized according to customer requirements. When there is no need to open a new mold, the cycle only takes about 2 weeks, and some spare registers are reserved in the system for customers to add new functions.
