Applied range:
1. Relay is a kind of automatic electric appliance, it is suitable for long distance connected and points off, small dc capacity control circuit, and in the electric drive system for control, protection and signal conversion.
2. Relay input is usually electric power flow, voltage, etc., can also be non-electricity, such as temperature, pressure, speed, when the output is the contact action from the electrical signals or the parameters of the output circuit changes.
3. The characteristics of the relay is when the quantity of the input to a certain program, the output will change of step.
Interface Description:
VCC : Positive power supply (voltage required by the relay, there 5V.9V.12V and 24V choice)
GND : Enter the negative
IN :High level control relay (available MCU I/O port control)
Another description of the interface directly to the circuit board, the middle piece of the line is common, That end of the bias is normally closed relay interfaces, and the other end is normally open relay interface.
The concept used by the relay:
Electromagnetic relays generally consists of core , coil , armature , contacts and other components of the reed. As long as the coil ends with a certain voltage , will flow through a coil of current , resulting in an electromagnetic effect , the armature will be attracted to overcome the electromagnetic force of the suction action of the return spring to pull the core, so as to drive the armature dynamic contact with the stationary contact (normally open contact) pull. When the coil power, the electromagnetic suction disappeared, the reaction force of the spring armature will return to the original position, so that the moving contact with the original stationary contacts (normally closed contacts) released. Thus pull, release, so as to achieve conduction in the circuit, the purpose of cutting. For the relay, "normally open, normally closed" contact, it can be distinguished: the relay coil is not energized in a disconnected state of stationary contacts, called "normally open contact"; in the ON state of said stationary contacts is "normally closed contact." Relay circuits generally have two shares for low-voltage and high-voltage control circuit operating circuit.
