Signal Isolator is used to adjust and isolate various signals of field instruments and convert them into standard signals acceptable to computers, DCS, PLC, etc., or special signals designated by users. Isolators are mainly used to electrically isolate telecontrol equipment and operating equipment. They play the role of electrical isolation, protect the next control loop, and also play the role of signal transmission and anti-interference.
The principle of the signal isolator is to modulate and convert the signal of the transmitter or instrument through semiconductor devices, and then realize isolation conversion through optical or magnetic sensing devices, and then demodulate and convert back to the signal before isolation. At the same time, the isolated signal and power supply are isolated to ensure the absolute independence between the converted signal, power supply and ground, especially suitable for use with equipment and instruments requiring electrical isolation.
The signal will encounter various interferences in the transmission process. In order to ensure the stability of the signal, signal isolator will be used to isolate the interference and avoid signal distortion. It is widely used in major projects in oil field, petrochemical, manufacturing, electric power, metallurgy and other industries.
1. Eliminate the influence of grounding loop
Due to the potential difference between the signal reference points between the instrument and equipment, a grounding loop will be formed between them, which will often cause interference and distortion in the signal transmission process. To ensure the stable and reliable operation of the system, the "grounding loop" problem must be solved in the process of system signal processing.
2. Eliminate high-frequency electromagnetic interference
To realize monitoring and control in the industrial production process, various automatic instruments, control systems and actuators are required. After the signal transmission between them constitutes a system, it is often found that mutual interference between instruments and equipment causes system instability or even misoperation. Eliminating electromagnetic interference can ensure signal stability.
3. Resolve the signal mismatch problem before the device
Two devices that need channel signal connection can not be connected normally due to different signal output types and received signals. At this time, isolators can be used to achieve signal conversion.
4. One channel signal is distributed to multiple channels
On some occasions, we need to transmit signals to multiple systems, such as control system and display system. At this time, we can choose the function of one in and many out of the isolator to achieve this, which can not only ensure the signal distribution on the site, but also achieve signal isolation, which is simple and convenient without losing accuracy.
