1. Replace small contactors
The contacts of the intermediate relay have a certain load capacity, and when the load capacity is relatively small, it can be used to replace the use of small contactors, such as electric roller shutters and the control of some small household appliances. The advantage of this is that it can not only play the purpose of control, but also save space, so that the control part of the electrical appliance is more exquisite.
2. Increase the number of contacts
This is the most common use of intermediate relays, for example, when the contact of a contactor in a circuit control system needs to control multiple contactors or other components, but an intermediate relay is added to the line.
3. Increase contact capacity
We know that although the contact capacity of the intermediate relay is not very large, it also has a certain load capacity, and the current required for its drive is very small, so the contact capacity can be expanded with the intermediate relay. For example, it is generally not possible to directly use the output of inductive switches and transistors to control electrical components with large loads. Instead, an intermediate relay is used in the control line to control other loads through the intermediate relay to achieve the purpose of expanding the control capacity.
