How Should The Relay Be Wired?

Because the main purpose of Power Relay is to control the strong electricity with weak current. (including low voltage control high voltage, small current control high current). The effect is achieved by controlling the on and off of its own coil to turn its contacts on and off. (Popular point is to control the magnet to suck or not, and the magnet to control the contact switch)
Therefore, the connector of the relay includes the contact connector of its control circuit and the connector that controls its coil.
If you still have any questions, please read the instructions carefully, or the relay itself, we are Power Relay Supplier, can help you solve all doubts.

Pull-in Voltage And Release Voltage Of High Power Relays

图片
As a  Relay Electronics Manufacturer , let's talk about two concepts about relays. Rated operating voltage, pull-in voltage, release voltage, contact resistance, dielectric withstand voltage, and insulation resistance are six commonly used parameters for relays. Pull-in voltage High Power Relays work when they are not connected to the rated voltage, so the pull-in voltage is the minimum voltage at which the relay can pick up. When designing the circuit, generally leave enough voltage, but not too much than the rated voltage, so that the relay can output stably, and it is also a kind of protection for the relay. 2. Release voltage High Power Relays are always released, so this release voltage is the maximum voltage at which the release action occurs, specifically the coil voltage at which the armature and contacts return to their original position. The pull-in voltage can be measured in this way. If it is a DC input relay, it can be directly used as a DC power supply....

Basic relay contacts parameters terminology

图片
1.Contact forms : they're the arrangements of relay contacts. The basic contact arrangements are shown in table below, the multi-contact arrangments can be ratiocinated. 2.Contact resistance : it is the total resistance between the contacts, the terminals and spring jointed with contacts, generally shown in mΩ. 3.Contact voltage drop : it generally is, in the load circuit, the total voltage drop between contacts,springs jointed with contact and the terminals. It is generally described as the voltage drop value under the regulated current, for example 50mV(measured in 10A). 4.Contact material : it is the material used in contacts and generally shown in chemistry formula, for example, AgNi represents silver-nickel alloy contacts.  5.Contact rated load : it generally refers to the load of which the contacts can switch reliably under the certain regulated conditions. Generally it is shown as the combination of the voltage and the current. The loads listed in the catalogue ar...

Power Relay Solution In Case Of Insufficient Voltage

图片
Once the voltage applied to the coil is insufficient, the  Power Relay  will not work, or the operation will be unstable, which will cause the durability of the contact to decrease or the contact point such as welding to be blocked. In particular, in a large motor or the like, when the power is turned on, the voltage applied to the Power Relay coil sometimes drops at the moment of a load operation in which a large inrush current is generated. If the Power Relay operates in a low voltage state, even if it is a vibration or shock value within the specifications specified in the specifications and catalogues, the relay may malfunction. Therefore, apply a rated voltage to the coil of the relay. For fluctuations in the power supply voltage, apply a voltage to the coil that each relay can fully operate. If a voltage is applied to the coil that does not allow the relay to fully operate, the coil will be abnormally heated, causing the coil to burn out. In addition, if a motor, ...
