PHARPS32200000 F8-G2B9B3B6 Input/Output Module
PHARPS32200000 F8-G2B9B3B6 generally require that the signal line must have a unique reference ground, shielded cable encountered there may be occasions of conduction interference, but also in the local or control room to uniquely grounded, to prevent the formation of a “ground loop”. Signal source grounding, the shield should be grounded in the signal side; not grounded, it should be grounded in the PLC side; signal line in the middle of the connector, the shield should be firmly connected and insulated, be sure to avoid multi-point grounding; more than one measurement point signal shielded twisted-pair cable and multi-core twisted pair of the total shielded cable connection, the shield should be connected to each other and insulated, select the appropriate grounding point at a single point of contact.
PHARPS32200000 F8-G2B9B3B6 frequency converter interference processing generally have the following ways: add isolation transformer, mainly for the conduction interference from the power supply, can be the vast majority of the conduction interference blocked before the isolation transformer. The use of filters, filters have a strong anti-interference ability, but also has to prevent the interference of the equipment itself is transmitted to the power supply, and some also has a spike voltage absorption function. The use of output reactors, in the frequency converter to the motor between the increase in AC reactor is mainly to reduce the frequency converter output in the energy transfer process line produces electromagnetic radiation, affecting the normal work of other equipment.
PHARPS32200000 F8-G2B9B3B6 Realizing the automation of medium- and low-voltage distribution networks can improve the quality and reliability of power supply. Realizing the automation of medium and low voltage distribution network can reduce the number of failures, narrow the scope of accidents, shorten the time of accidents, and provide an effective basis for the restoration of power supply, rapid analysis, diagnosis, and reporting of the causes of accidents. Realizing the automation of medium and low voltage distribution network can improve the economic benefits of the whole power system: reduce the labor intensity of maintenance personnel; reduce the number of operators; enhance the maintenance-free nature of the power system; and help to improve the safety and health of the equipment and prolong its service life.
