Relay

Reed Relay

The reed relay consists of a switch with magnetic contacts that move under the influence of an external magnetic or the induced field from its solenoid. They have faster switching speed compared to the electromechanical ones but their switching current and voltage is lower mainly because of its contacts thickness. As you can see above […]

DPST Relay – Double Pole Single Throw

The Double Pole Single Throw DPST relay is the equivalent of 2 SPST switches (NO Normally Open and NC Normaly Closed) and can be used to switch 2 different loads. We have 2 scenarios depending on the type of relay without voltage on coil: with a NO the loads will be OFF because the current […]

DPDT Relay – Double Pole Double Throw

The DPDT relay (Double Pole Double Throw) is quite interesting and can be used in various scenarious, including for changing the direction of a motor as you can see in the picture below. It has 2 terminals and 4 connectors and you can look at the DPDT relay as the equivalent of 2 Single Pole […]

SPDT Relay – Single Pole Double Throw

The Single Pole Double Throw SPDT relay is quite useful in certain application because of its internal configuration. It has one common terminal and 2 contacts in 2 different configurations: one can be Normally Closed and the other one is opened or it can be

NC SPST Relay – Normally Closed Relay

The NC Normally-Closed SPST (Single Polse Single Throw) relay has an initial closed circuit state when no current is applied to its internal coil therefore it connects the power to the load (fan, light bulb, etc). When voltage is applied to the coil of the relay the internal switch goes to the open position and […]

NO SPST Relay – Normally Open Relay

The NO Normally-Open SPST (Single Pole Single Throw) relay has an opened circuit state when no current is applied to its coil so basically it disconnects the power to the load in the inactive state. When current is applied to its coil the generated magnetic field switches the armature and closes the contact so you […]

Common Types of Relay

You can choose from a wide range of relays but do you know what type to use in your project? Well, sometimes is hard to choose, especially if you’re not sure which model you need or how a specific one works. In this article we will learn about different types of relay and what to […]

Run/Stop Relay Circuit

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after an outage. In such cases, unwanted or unexpected motion is a risk to life or limb. The most simple solution to this problem […]
