What is the composition structure of an isolator

1.3 Power Supply:

 Isolators typically require a dedicated power source to supply operating voltage. This power source can be an AC power supply, a DC power supply, or another type of power source, depending on the design and requirements of the isolator.

1.4 Control Circuit:

The control circuit is designed to monitor input signals and process output signals as required. It may encompass functions such as amplification, filtering, and logical decision-making to ensure that the output signal meets the desired specifications.

1.5 Enclosure and connectors:

Isolators typically have an enclosure to protect the internal circuitry and provide a secure interface for connections. The enclosure is usually made of insulating material to ensure effective isolation.

The structure of an isolator consists of three main parts: the operating area, the filtration system, and the enclosure. The operating area is the core of the isolator and typically includes a pair of gloves and an operating panel. The filtration system is used to filter out microorganisms and particles from the air, often comprised of high-efficiency filters and fans. The enclosure serves as the external protective layer, isolating the operating area from the surrounding environment.

It should be noted that different types of isolators may vary in their specific structures. For example, some isolators may employ multi-layered circuit board structures and intricate wiring designs to enhance their electrical performance and interference resistance. Additionally, the accuracy, bandwidth, and noise characteristics of isolators can differ due to variations in their internal circuits and components.

In summary, the structure of an isolator is designed based on its operating principles and performance requirements. While different isolators may exhibit variations in their structures, they generally consist of fundamental components such as input ports, output ports, isolation elements, and power modules.

2.The function of the isolator

2.1 Prevent interference signals from passing through

Within electronic devices, there exists a plethora of integrated circuit chips, including discrete components. These integrated circuit chips generate copious amounts of high-frequency pulse waves, such as square waves and sawtooth waves, as well as noxious stray currents and stray energy in the form of noise voltage. If these high-frequency pulse waves and noise voltage are directly introduced into the circuitry, it would adversely affect the normal operation of the electronic device, potentially resulting in damage.

2.2 Cause the circuit to function properly

When electronic devices malfunction, they can generate a significant amount of high-frequency pulse waves and noise voltage, as well as various undesirable stray currents and energy. If these high-frequency pulse waves and noise voltage are directly connected to the circuit, it will also affect the normal operation of the electronic device and may potentially lead to the occurrence or exacerbation of faults, resulting in even greater losses or even rendering the electronic device unusable.

2.3 Ensure the protection of the devices from any potential damages

For some crucial components, their operating temperatures are generally quite high (for example, the temperature of a CPU can reach 150°C to 200°C). If these components are subjected to prolonged operation in high-temperature environments, it is highly likely that the aging and degradation of their internal insulation materials will significantly shorten their service life.

2.4 Improving the reliability of the system

Sometimes, when a system malfunctions, it is not necessarily due to a fault in a specific component, but rather a problem that affects the entire system (such as a power supply abnormality). In such cases, if the issue can be promptly identified and the various components of the system isolated, it can effectively eliminate potential hidden faults within the system and ensure an improvement in its reliability.

The specific structure and composition of isolators may vary depending on the brand, model, and application. For detailed information regarding a particular isolator, it is advisable to consult the relevant product manual, standard documentation, or seek advice from professionals in the field.

3.The necessity of the isolators

In industrial settings, there are various sizes of detection and control systems consisting of automation instruments, monitoring devices, and other components. These systems need to exchange a variety of signals. During the production process, both the control and monitoring systems may encounter challenges such as environmental interference, short circuits, overvoltage, unidentified pulses, signal mismatch, and mutual interference between signals. These situations can lead to system instability, incorrect operations, or even failure to function. Therefore, having isolators that protect lower-level control loops, attenuate environmental noise, suppress grounding or equipment interference, and provide current and voltage limitation is essential in safeguarding the input-output and communication interfaces of the control systems.

4.Product purchase

When selecting an isolator, in addition to determining its functionality and compatibility with the front and back-end interfaces, users need to carefully consider many parameters such as accuracy, output ripple, temperature drift, power consumption, and response time.

In summary, the main function of an isolator is to provide a clear break point in a circuit. Its purpose is to protect electrical equipment and ensure the safe operation of the electrical system, providing a secure guarantee for equipment maintenance.
