Time relays

As a professional electrical wholesaler, we provide access to a wide range of control equipment used in modern industrial automation systems. In this category you will find single-function and multi-function time relays. These are specialist devices designed for time control of installations and machines. Check out the time relays offered and learn about their functions and applications.

Time relay - a popular variant of an electrical relay

Electrical relays are electrical or electronic devices used to induce a desired, sudden change in state in one or more circuits. They play a key role in the automation of various processes. There are many types of relays. They differ in terms of construction, and therefore also in function. One of the most commonly used types of electrical relays, especially in construction, are time relays. These devices are equipped with a timer that measures the delay time and a mechanism that opens or closes an electrical circuit after a programmed time has elapsed.

Application of time relays

The basic role of a time relay is delayed switching on and off after a specified time of an installation or machine - cyclically or with adherence to established breaks. Time relays, through precise control of time and sequence of operations in applications, enable control of, among others: • lighting, • ventilation system, • heating, • signaling system. Time relays are currently standard equipment of welding robots, transport systems and automated assembly lines.

Benefits of using time relays

Thanks to the use of time relays, systems and machines can operate in an unattended manner and with maximum precision, efficiency, economy and reliability.

Types of time relays

The simplest type of time relay is the mechanical model. It is based on a spring mechanism. It is not suitable for applications requiring maximum precision. The second type is the electrical time relay. Equipped with a capacitor and a resistor, it measures time with high accuracy. The most precise and flexible are electronic time relays. These are advanced devices, equipped by manufacturers with integrated circuits and microprocessors.
