WR310LE is a kind of electrical equipment used to control the working state of devices. It is widely used in the fields of industrial, medical, transportation, automation, agricultural machinery and other fields. Here we will introduce the application field and working principle of WR310LE.Application FieldWR310LE is mainly used in the field of industrial automation, especially in application scenarios where a large number of simple control tasks need to be achieved. For example, in the three-phase AC motor control system, WR310LE can be used to relay the voltage steady signal. At the same time, it can also be used to realize digital switching power supply and fault detection of overload protection.In the medical field, WR310LE is often used to replace medical instruments for medical examinations. With its advanced signal isolation, high-precision measurement, and strong anti-interference ability, WR310LE can realize fast and accurate measurement of various physical quantities such as temperature, pressure, and corrosion. What\'s more, by attaching an aircraft-type environmental monitoring box, it can even monitor the environment of some closed places for the convenience of search and rescue and the safety of medical personnel.In the transportation industry, WR310LE can be used to complete the control requirements of its transportation systems, including monitoring the running speed of locomotives and controlling the opening and closing of doors.Finally, WR310LE can also be used to help farmers in agricultural machinery. It can be used in combination with advanced sensors, providing intelligent measurement and warning functions to the machine, and ensure the efficiency of agricultural production.Working PrincipleWR310LE mainly uses two relays to realize the function of timing on and off. Its relays are an asymmetric type. When a single phase voltage is applied, the two switch contacts move in opposite directions, and obtain external control through the adjustment of the operating time, thereby different control effects can be obtained.The main working principle is that when the instantaneous power at the AC input terminal exceeds the safe level, the flow of current is reduced, the capacitor C1 is quickly charged, and the voltage at both ends of C1 is close to the instantaneous power. At this time, the voltage at both ends of C1 is applied to the SCR1, so that the SCR1 is controlled to enter conduction state, which causes the current output of the thyristor to become zero, and then causes the relay contact two to turn from closing to opening, and the output is interrupted.Meanwhile, the voltage generated by the coulomb capacitor C2 is amplified through the voltage amplification module OP, thereby generating a certain voltage on the base of the transistor TR1, and then TR1 is turned on, so that the two relays are turned off, and the output control circuit is switched on, thereby completing the on-off control.ConclusionTo sum up, WR310LE is an ideal electrical device to complete a large number of simple control tasks. By controlling the timing on and off of its relays, different applications can be completed. At the same time, its working principle is also very simple, which can be easily implemented by adjusting the operating time. All in all, WR310LE has broad application prospects in many fields, greatly improving the control efficiency and convenience of the equipment.
