ICS TRIPLEX T9432 Inductive current coupling

ICS TRIPLEX T9432 ground including system ground, shielded ground, AC ground and protective ground, etc., grounding system disruption to the PLC system interference is mainly uneven distribution of the potential of each grounding point, the ground potential difference between different grounding points, resulting in ground loop current, affecting the normal operation of the system. For example, the cable shield must be grounded at one point, if the cable shield ends A, B are grounded, there is a ground potential difference, there is a current flowing through the shield. When an abnormal state occurs, such as a lightning strike, the ground current will be greater.

ICS TRIPLEX T9432 shield, ground wire and earth may constitute a closed loop, under the action of the changing magnetic field, there will be induced currents in the shield, through the shield and the coupling between the core wires, interfering with the signal loop. If the system ground is confused with other ground processing, the resulting ground loop current may generate unequal potential distribution on the ground line, affecting the normal operation of logic and analog circuits within the PLC.

ICS TRIPLEX T9432 logic voltage interference tolerance is low, the distribution of logic ground potential interference is likely to affect the PLC’s logic operations and data storage, resulting in data confusion, program run or crash. Analog ground potential distribution will lead to a decline in measurement accuracy, causing serious distortion of the signal measurement and control and false action.
