Relay

Relays have various types that adapt to the machine that will be used. For this reason, the following is a description of the types of relays, and how they work to make it easier for you to use them.

Relay Type

1. Single Pole Single Throw Type Relay

Single Pole Single Throw is a relay that has four terminals, two terminals as contact points (switch) and two other terminals for electromagnetic coils. Two terminals are used as contact points one as pole and one as throw.

2. Single Pole Double Throw Type Relay

This type of relay has five terminals, three terminals are used as contact points (switch) and the other two terminals are used as electromagnet coils. Three terminals are used as point contacts, one as pole and two as throws.

3. Double Pole Single Throw Type Relay

This type of relay has six terminals, four of which are point contact terminals (switch) and the other two terminals are used as electromagnet coils. The four terminals used as point contacts consist of two pairs of single pole double throw switches.

4. Double Pole Double Throw Type Relay

This type of relay has eight terminals, six terminals are used as contact points (switch) and two terminals are used as electromagnetic coils. The six terminals used as point contacts consist of two pairs of single pole double throw switches.

How Relays Work

Relays work to control the flow of electric circuits by opening and closing a circuit. When an electrical circuit is opened, a part of the circuit is closed. This one tool is usually used to control the flow of small electricity in the circuit. This tool can be used to control the flow of large electricity as long as its use is combined with an amplifier. The use of this one tool is usually accompanied by a protector to prevent damage to the equipment by detecting irregularities in the flow of electricity. Its use can also be accompanied by a starting coil, temperature control elements, pilot lights, and also sound alarms. Inclusion with other devices is usually adjusted to the existing needs.

That's a discussion of the types of relays and how they work. Some relay products that you can use as a reference to buy relays such as Schneider relay products, Mitsubishi relays, Chint relays, and Siemens relays.
