Audited Supplier Principle of multifunctional signal isolator
The working principle of the multifunctional signal isolator mainly includes the following steps:
1. Signal conversion: First, the signal isolator converts the signal of the transmitter or instrument through the modulation of the semiconductor device.
2. Signal isolation: Then, the input signal is isolated from the output signal through the optical or magnetic sensing device for isolation conversion.
3. Signal demodulation: Next, demodulation conversion is performed to convert the isolated signal back to the original signal before isolation.
4. Power isolation: At the same time, the isolated signal power supply is also isolated to ensure that the converted signal, power supply, and ground are absolutely independent.
5. Filtering and matching: In addition, the signal isolator also filters the interference signal superimposed on the measured value, and then matches the signal according to the input and output requirements of the control system.
Advantages of a multifunctional signal isolator
The advantages of multi-function signal isolators mainly include the following aspects:
1. Cost effectiveness: In most cases, it is cheaper to use signal isolators + non-isolated cards than to use isolated cards.
2. Superior performance: The signal isolator is more superior in isolation ability and electromagnetic interference resistance.
3. Flexible application, easy to use: the signal isolator application is flexible, and it has model conversion and signal distribution functions, which is more convenient to use.
4. Easy maintenance: The signal isolator usually has single channel, double channel, one in two out and other channels, and the channels are completely independent from each other, which makes the configuration and daily maintenance of the system more convenient.
5. Protect the control loop at the lower level: the signal isolator can protect the control loop at the lower level, reduce the impact of environmental noise on the test circuit, and effectively inhibit the interference of common ground, frequency converter, solenoid valve and unknown pulse on the equipment; At the same time, it has the function of limiting voltage and current, and it is the faithful protection of transmitter, instrument, frequency converter, electromagnetic valve input and output and communication interface.
6. Prevent ground loop: In addition to suppressing interference through isolation, the signal isolator can also break the interference ground loop to protect the purity and stability of the control signal.
7. Improve the signal load capacity: In the process of long-distance transmission of analog signals, the isolator is installed to amplify the signal, which can effectively improve the signal load capacity to ensure the accuracy and reliability of the transmission signal.
8. Improve system stability: the signal isolator can effectively solve the interference and stability problems of signal transmission, and improve the efficiency and reliability of remote control.
