PFSA107-Z64 3BSE065365R2 Relay Contactor

PFSA107-Z64 3BSE065365R2 is a product developed on the basis of relay control and computer control. Since the end of the 1960s, after the United States first developed and used programmable controllers, countries all over the world, especially Japan and the Federal Republic of Germany, also developed their own PLC (programmable logic controller), therefore. Therefore, compared with the traditional relay contactor control system, the author believes that the use of PLC to realize the squirrel cage asynchronous motor starting and braking control is the most sensible choice.

PFSA107-Z64 3BSE065365R2 start, press the start button SB1, X400 normally open contacts closed, Y430 coil on and self-locking, KM1 coil on, the main contact suction, the motor is strung into the current-limiting resistor R began to start, at the same time, the two pairs of normally open contacts Y430 closed, when the motor speed rises to a certain value, the normally open contacts of KS1 closed When the motor speed rises to a certain value, the normally open contact of KS1 closes, the normally open contact of X402 closes, the coil of M100 turns on and self-locking, a pair of normally open contacts of M100 turns on the coil of Y432, the coil of KM3 is electrically active and the main contact is suctioned, and the starting resistance is shorted, and the motor speed rises to a certain value and then puts it into stable operation.
