Analysis and Suppression of DCS Signal Interference Causes
At present, various control systems used in automation systems may be in harsh electromagnetic environments formed by strong electrical circuits and equipment. At the construction site, there is often interference in signal transmission between electrical equipment, instruments, DCS control systems, and DCS systems, which can cause system instability or even misoperation, and must be taken seriously.

Isolated safety barrier manufacturer: Precautions for installation of isolated safety barrier
The isolated safety barrier produced by the isolation safety barrier manufacturer is a device used for intrinsically safe explosion-proof systems and used for safe isolation of field instruments. Explosion-proof systems and explosion-proof electrical equipment use isolated safety barriers in the design. Installed in a safe place, is a device that contains intrinsically safe circuits and non-intrinsically safe circuits.

Isolated safety barrier manufacturer: Precautions for the use of isolated safety barrier
The main function of the isolated safety barrier produced by the isolation safety barrier manufacturer is to limit the dangerous energy to enter the safe place, that is, to limit the voltage and current to enter the dangerous place. The zener z is used to limit the voltage. When the circuit voltage is close to the safe limit value, the voltage across the tube always remains below the safe limit value. So, here's a look at the use of isolated safety barriers.
