Hall Current Sensor 10A 20A 30A 50A 100A 150A Current Transducer 4-20mA 0-10V Hall Current Transmitter

Product Description

1.  DC signal isolators are a type of equipment widely utilized in the field of industrial automation. Their primary function is to isolate, convert, and transmit DC signals. During the contemporary industrial production process, signals need to be transmitted among various automatic instruments, control systems, and actuators. These signals include both weak small signals and powerful large signals, and their frequencies vary. In such a complex environment, the problem of signal interference becomes particularly prominent, and thus DC signal isolators emerged to address these issues.

    Introduction to DC signal isolators

    The principal function of DC signal isolators is to isolate and amplify the input DC signal and convert it into the necessary output signal. It can effectively resolve problems such as ground loop interference and natural interference, ensuring the stability and accuracy of signal transmission. Specifically, DC signal isolators possess several crucial functions:

    Signal Isolation: Disrupt the electrical connection between the input and output through methods such as photoelectric isolation or transformer isolation, thus preventing local loop interference.

    Signal Conversion: Transform the input DC signal into other types of signals, for example, convert a voltage signal into a current signal, and vice versa.

    Signal Amplification: Amplify the input weak signal to meet the signal requirements of subsequent equipment.

    Protection Function: Provide overload protection and short-circuit protection to prevent equipment damage resulting from abnormal circumstances.
