How to judge whether the relay is normal:
1) The detection of the electromagnetic relay mainly measures the DC resistance of the coil and the normally open and normally closed contacts.
2) It is mainly the contacts, and the pull-in of the coil is also very important.
Relay (English name: relay) is an electrical control device, which is an electrical appliance that makes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the specified requirements.
It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
As a control element, to sum up, the relay has the following functions:
1) Expand the control range: For example, when the control signal of a multi-contact relay reaches a certain value, it can switch, break, and connect multiple circuits at the same time according to different forms of contact groups.
2) Amplification: For example, sensitive relays, intermediate relays, etc., with a very small amount of control, can control circuits with high power.
3) Integrated signal: For example, when multiple control signals are input to the multi-winding relay in a prescribed form, the predetermined control effect can be achieved through comparison and synthesis.
4) Automatic, remote control and monitoring: For example, the relay on the automatic device can form a program control circuit together with other electrical appliances to realize automatic operation.
