ABB UAD149A1501 3BHE014135R1501 is mainly generated by the internal components of the system and circuitry between the mutual electromagnetic radiation, such as logic circuits radiate to each other and their impact on the analog circuitry, analog ground and logic ground and the mutual impact of the components of the mutual mismatch between the use and so on. This all belongs to the PLC manufacturer of the system within the electromagnetic compatibility design of the content, more complex, as the application of the department is unable to change, may not have to consider too much, but to choose to have more application achievements or tested system.

ABB UAD149A1501 3BHE014135R1501 In order to ensure that the system is free from or reduce internal and external electromagnetic interference in the industrial electromagnetic environment, it is necessary to start from the design stage will take three aspects of the suppression measures: inhibit the source of the interference; cut off or attenuate the propagation pathway of the electromagnetic interference; to improve the anti-jamming ability of the device and system.

ABB UAD149A1501 3BHE014135R1501 control system interference is a systematic project, requiring the manufacturing unit to design and produce products with strong anti-interference capability, and depends on the use of the department in the engineering design, installation, construction and operation and maintenance to be considered comprehensively, and combined with the situation of a comprehensive design to ensure that the system’s electromagnetic compatibility and operational reliability. Reliability. Specific engineering anti-jamming design, should be mainly the following two aspects.
