Finder general relayCan the coil be replaced? Finder general relay refers to the relay that can be used in one or more fields. A relay is an electrical appliance that changes the controlled quantity in a predetermined step in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. According to the principle, finder general relay can replace coils with different properties, so it can be made into various relays. The relay is composed of several high-quality sealed small relays with low coil voltage, which is moisture-proof, dust-proof, uninterrupted and highly reliable.

Other relay coil characteristics

Voltage relay: the relay whose action of contact is related to the action voltage of coil is called voltage relay, which is used for voltage protection and control of electric traction system. When in use, the coil of voltage relay is connected in parallel with the load.

Features: the coil has many turns and thin wire diameter.

Classification: according to the type of coil current, it can be divided into AC and DC voltage relays, and according to the pull-in voltage, it can be divided into overvoltage, undervoltage and zero voltage relays.

Current relay: the relay whose action of contact is related to the action current of coil is called current relay. When in use, the coil of the current relay is connected in series with the load.

Features: coil turns are small and thick.

Classification: according to the type of coil current, it can be divided into AC and DC current relays, and according to the magnitude of pull in current, it can be divided into overcurrent and small current relays.
