How to control ac motors with dc 24V voltage
24 v dc voltage cannot be applied to ac 24 v ac contactor, and buy less than 24 v ac contactor, can use a inverter to 24 v dc into 220 v ac voltage, and buy a 220 volt ac contactor with a button, the circuit connection is ok,
Weak electricity controls strong electricity, which is the basic requirement of control. The voltage of DC24V can operate the coil of the relay, and then control the motor's three-phase ac contactor. It can also be used by PLC relay output module to operate the motor's three-phase ac contactor. In the motor start-up and protection circuit, the contactor is the component that controls the engine's stop. High power motor, which can be operation by the frequency converter, passive contact with remote start frequency converter, and drive the passive contact, can also be DC24V dc intermediate relay.
The 24V contactor is also very expensive, with intermediate relays, and then use the intermediate relays to control the contactor
