In principle, relays and contactors operate in the same way - by switching on they designed to transmit the signal further. Depending on the design, it may be a current or voltage signal. Contactors are devices for switching power supply circuits, while relays transmits a low-voltage signal or signal with a zero potential. The contactors are connected to electrical devices such as electric motors, while relays are used to provide control signals, e.g. to or from PLCs.
Contactor-relay systems are called systems in which the contactors are executive elements (they turn on and off the appropriate working circuits at the right moment), while relays control the operation of contactors causing the coils of contactors to be charged depending on specific factors.
