The shortcomings of control relay Today, relay has been applied to various fields of household and industrial control. They have higher reliability than previous products. However, it also brings some problems. For example, most control relays are easily damaged due to long-term wear and fatigue. Moreover, the contacts of the relay are easy to produce arc, and even fuse together to cause misoperation, which will cause serious consequences. Moreover, the control box of a specific equipment equipped with hundreds of relays will be huge and cumbersome. In the case of full load carrying, large relays will generate a lot of heat and noise, and also consume a lot of electrical energy. And the relay control system must be manually wired and installed. If there is a simple change, it will also take a lot of time, manpower and material resources to reform, install and debug.



2、 Advantages, characteristics and functions of programmable controller



The programmable controller is famous for its small size and powerful functions. It can not only easily complete the functions of sequential logic, motion control, timing control, counting control, digital operation, data processing, etc., but also establish the connection with the digital and analog quantities of various production machinery through the input/output interface, so as to realize the automatic control of the production process. Especially now, due to the arrival of information and network era, the function of PLC has been expanded, so that it has strong networking communication ability, and is more widely used in many industries.



1. Sequential control



Sequence control is a basic and widely used field of PLC. The so-called sequential control is to make each executive mechanism in the production process automatically act in sequence according to the sequence of the process flow and under the action of the control signal. Because it also has the advantages of flexible programming design, fast speed, high reliability, low cost and easy maintenance, it can completely replace the traditional relay contactor control system in the realization of single machine control, multi cluster control and production process control. It mainly controls the mechanical moving parts for corresponding operation according to the operation buttons, limit switches and other on-site command signals and sensor signals, so as to achieve automatic production line control. Typical applications include the control of automatic elevators, the automatic opening and closing of electromagnetic valves on pipelines, and the sequential starting of belt conveyors. For example, the raw material mixing system of our branch factory uses the sequence control function of PLC.



2. Closed loop process control



In the past, PID analog regulator composed of hardware circuit was used to realize open and closed loop control for analog quantity of process control. Now it is completely possible to use PLC control system and analog control module. Its functions are completed by software. The accuracy of the system is determined by the number of bits and is not affected by the elements. Therefore, it is more reliable, easy to achieve complex control and advanced control methods, and can control multiple control loops and multiple control parameters at the same time. For example, temperature, flow, pressure, speed, etc. in the production process.
