How to Select the Right Time Relay for Your Project

29th Apr 2025

A time relay is a device responsible for dominating the power flow of a circuit via electromagnetism. Here, there is a wire coil wrapped around an iron core. Once power flows across the circuit, a magnetic field is created in the electromagnet. This magnetic field then takes charge of attracting or repelling another magnet that is attached to a time relay switch located within the device. This gives you control by managing how long the current flows through the coils before the stop. This guide will teach you the steps and ways of picking the right time relay for your electrical projects. It will cover the following: – How a time relay works – Applications of time relays – How to choose the right time relay The Time Relay Working Principle Electromagnetism is the central concept in the working principle of a programmable timer relay. In its structure, one relay coil is always on, while the other can be programmed, so it is off and on only when an electric signal is sent across from a device for control, such as a phone or PC. It is the turned-on coil that always receives power, ready to activate when it should. Meanwhile, the “off” coil receives power only upon the activation of the device. Then, it functions to pull in an armature that activates the circuit’s other end upon the flow of electricity. While the power remains off, this armature pulls back to where it was originally, no longer letting electricity to flow through the circuit. Hero […]
