1. Characteristics of tr--ning devices

The parameters of being adjusted include the four major parameters: liquid level, temperature, flow, and pressure commonly used in the industry;

The actuator has both the execution mechanism of the regulatory valve instrument, as well as the power drag actor such as the frequency frequency and the regulatory module;

In addition to changing the setting value of the regulator for step disturbance, the system can also create various disturbances through the hand operating valve;

A parameter can be evolved into a variety of regulatory circuits under different power sources, different actuators, and different process lines to facilitate discussions and compare the advantages and disadvantages of various regulation schemes;

Experiments of multiple variable control systems and specific process control systems;

Various control algorithms and regulatory laws can be controlled on open experimental software platforms;

Experimental data and charts are easy to store and call in the MCGS software system to facilitate the analysis and comparison of experiments after experiments;

In terms of signal processing, the entire set of signal interfaces are also reserved, which can be used for future system expansion, such as: live bus, DCS and other control systems;

In the use of MCGS's powerful software system, a small LAN control can be formed.

In the overall tr--ning device, there is a temperature f--lure exclusion function, regulating valve f--lure function, card component f--lure exclusion function, etc.
