Types of programmable logic controllers
Programmable logic controllers are divided into two types according to their structure: integral type and modular type. According to the application environment, it is divided into two categories: on-site installation and control room installation. According to the word length, it is divided into bit, bit, bit, bit, 3 bit, bit, etc. From an application perspective, selection can usually be made based on control function or number of input and output points.
The integral programmable logic controller has a fixed number of /points, so users have less room for choice. The modular programmable logic controller used in small control systems provides a variety of /cards or plug-in cards, so users can compare Reasonably select and configure the number of points/points of the control system, and the function expansion is convenient and flexible. It is generally used in large and medium-sized control systems.
Input/output type
Switching quantity
Switching quantity mainly refers to the input value and the output value. It refers to the auxiliary point of a device, such as the relay of the thermostat of a transformer. auxiliary point (displacement after transformer over-temperature), auxiliary point of valve cam switch (displacement after valve switch), auxiliary point of contactor (displacement after contactor action), thermal relay (thermal relay action) (post-displacement), these points are generally transmitted to the or comprehensive protection device. The power is generally provided by the or comprehensive protection device. It does not have power itself, so it is called a passive contact, also called the input of the or comprehensive protection device.
, digital quantity
Physical quantities that are discrete in time and quantity are called digital quantities. Signals representing digital quantities are called digital signals. Electronic circuits that work under digital signals are called digital circuits.
For example:
When an electronic circuit is used to record the number of parts output from an automatic production line, a signal is given to the electronic circuit every time a part is sent out to make it count. However, when there are usually no parts sent out, a signal is added to the electronic circuit. The signal is, where the count is. It can be seen that the signal of the number of parts is discontinuous in both time and quantity, so it is a digital signal. The smallest unit of quantity is one.
, Analog quantity
Physical quantities that are continuous in time or numerical value are called analog quantities.
The signal representing the analog quantity is called an analog signal. Electronic circuits that work under analog signals are called analog circuits.
