EC3211NNN1NNAH TOSHIBA 过程回路控制器

EC3211NNN1NNAH single-loop controller is a digital control instrument with microprocessor as the calculation and control core and corresponding software, which is similar to the conventional analog controller in appearance and use. It is also called single-loop digital controller. Generally, a single-loop controller can accept multiple input signals, but only outputs one analog signal, which constitutes a single-loop direct digital control. Single-loop controller is generally composed of microprocessor, process input and output channel, front panel, side panel, power supply, digital communication system and other hardware parts, and software parts such as monitoring system and basic arithmetic programming system. It can be programmed by users to form various regulation rules, so it is also called “programmable controller”.

EC3211NNN1NNAH single-loop control consists of four basic links, namely, the controlled object (referred to as the object) or the controlled process (referred to as the process), the measuring and transmitting device, the controller and the control valve. The single-loop controller is the setting of the control system. For a control system that has been designed and installed, the transition process of the system can meet the most satisfactory quality index requirements by adjusting the controller parameters.

EC3211NNN1NNAH single-loop controller has two control loops: proportional-integral analog loop and proportional-integral temperature control loop. Single-loop feedback control system is referred to as single-loop control system. Among all feedback control systems, it is the simplest and most basic one, so it is also called … namely, 1 controlled object or controlled process, 2 measuring and transmitting devices, 3 controllers and 4 control valves. It is also a simple PID control. …
