What is Relay
A relay is a component that produces a predetermined transition in one or more outputs when the input amount reaches a specified condition. For electromagnetic relays, solid state relays and combined relays, it can be simply understood as: a predetermined electrical signal is applied to the input, and its output is switched on and off by a switch of the control circuit.
|Kind||Scope of application||Advantage|
|Communication relay||Generally used for communication and signal control|
The output of the disconnection has no leakage current and large load, no external heat sink is needed.
|General purpose relay||Generally used in home, industrial control and power control|
|Automotive relay||Suitable for the automotive sector|
|Sealed relay||Suitable for areas with harsh environments or high reliability requirements|
Solid state relay
|Suitable for areas with harsh environments, low noise requirements or high reliability requirements|
Long electrical durability
Good resistance to vibration and shock
|Combined relay||Areas that need to implement certain control functions||Have certain control logic|
otherwise stated, the parameters listed in the general product
specification are the initial values measured under standard conditions. The standard status is:
1) Temperature: 15 ° C ~ 35 ° C;
2) Relative humidity: 25% to 75%;
3) Atmospheric pressure: 86 kPa to 106 kPa.
Unless otherwise stated, the drawings provided by Meishuo generally use the first quadrant projection method.
