R-S108V01-16-24VDC-C10-1 High-speed Data Transfer Module

R-S108V01-16-24VDC-C10-1 control system sources of interference, mostly generated in the current or voltage drastic changes in the parts, the reason is that the current change produces a magnetic field, electromagnetic radiation on the equipment; magnetic field change produces current, electromagnetic high-speed electromagnetic waves. Usually electromagnetic interference is divided into common mode interference and differential mode interference according to the different modes of interference. Common mode interference is the signal to the ground potential difference, mainly by the grid string into the ground potential difference and space electromagnetic radiation in the signal line induced by the superposition of the common-state (same direction) voltage formation.

R-S108V01-16-24VDC-C10-1 common-mode voltage through the asymmetrical circuit can be converted into a differential mode voltage, directly affecting the measurement and control signals, resulting in component damage (this is the main reason for the high rate of damage to some of the system I / O module), this common-mode interference can be DC, can also be AC. Differential mode interference refers to the role of the signal between the poles of the interference voltage, mainly by the electromagnetic field in the space between the signal coupling inductance and unbalanced circuitry to convert the common mode interference in the formation of the voltage, this interference is superimposed on the signal, which directly affects the measurement and control accuracy.

The normal power supply of R-S108V01-16-24VDC-C10-1 system is powered by the power grid. Due to the wide coverage of the power grid, it will be subject to all space electromagnetic interference and the induction of voltage on the line. In particular, changes within the grid, knife switch operation surge, large power equipment start and stop, AC and DC drives caused by harmonics, grid short-circuit transient shock, etc., are transmitted to the original side of the power supply through the transmission line.
