Relay Used in Instruments
In the world of instrumentation, where accuracy and reliability are paramount, relays serve as indispensable components. These devices act as intermediaries between the control systems and the instruments, facilitating the efficient transfer of signals and the precise execution of commands. The utilization of relays in instruments ranges from simple laboratory equipment to complex industrial machinery.
In the digital input signal control loop, the relay has the function of isolation protection and remote monitoring, which not only prevents the 220V AC or 380V AC voltage from entering the 24V DC loop, but also can dynamically monitor and warn the motor operation, local/remote conversion, etc. In this kind of circuit, the electronic relay can not only control the opening and closing of the solenoid valve, but also control the opening and closing of the indicator light by using the different wiring forms of dry contact and wet contact.
One primary advantage of incorporating relays in instruments is their ability to handle high voltages and currents while providing galvanic isolation. This isolation is crucial in preventing interference between control circuits and the instrument itself, safeguarding the integrity of the measurements and ensuring the safety of both the equipment and personnel.
The versatility of relays further enhances their application in instruments. From time-delay relays that enable precise control over the timing of instrument operations to latching relays that maintain a particular state even in the absence of power, the adaptability of relays contributes to the customization of instruments based on specific requirements.
Therefore, in the automatic control of chemical instruments, the extensive use of relays can not only improve the safety and stability of the control system, but also reduce the work intensity of personnel to a certain extent and ensure the long-term stable development of the company.
