<h2>What are Timer Relays?</h2><p>A Timer Relay is a control relay with a time delay function built in. They serve as a combination of an electromechanical output relay and a control circuit, in which contacts can be opened or closed before or after a pre-selected timed interval. Relays can be normally open or normally closed and can be used to delay timed functions from milliseconds to hours or even days.</p><h2>Timer Relay or Electromechanical Relay?</h2><p>The difference between the timer relay and electromechanical relay is that when the output contacts open or close. On a conventional Control Relay, the contacts are opened or closed when a voltage is applied and removed from the coil, however, for timer relays the contacts will open or close before or after an intentional time period. When choosing the right Timer Relay, it is important to consider the kind of delay required for your application.</p><h2>What are the Types of Timer Relays?</h2><p>The most common timing function of Delay Relay are:</p><ul><li>On Delay (Time delay starts on the application of voltage)</li><li>Off Delay (When a voltage is applied the relay is ready to accept a trigger)</li><li>Single Shot (One-shot)</li><li>Interval On (Interval) and Flasher (On First / Off First)</li><li>Repeat Cycle (When a voltage is applied the relay contacts change state and the timer starts)</li></ul><p>When designing your application, it is important to understand the difference between the types of the Timer Delay Relays, considering what should initiate the delay and if it should start at the same time as the application, as well as when the voltage is released.

<p>A 12V timer relay is an electrical device that combines the functionality of a relay and a timer. It is commonly used to control the timing of an electrical circuit or system.</p><h2>How does a 12V timer Relay Work?</h2><p>The timer relay is powered by a 12V power source, which can be battery or an external power source. The relay has an input terminal that receives a control signal to initiate the timing operation. This control signal can come from a switch, sensor, or any other device that triggers the relay. Timing settings allow you to adjust the timing parameters according to your requirements. This includes setting the delay time, which determines how long the relay stays activated after receiving the control signal. Once the control signal is received, the timer relay activates an internal relay, which switches the electrical circuit or system on or off. The relay output contacts can handle higher currents or voltages than the control signal.</p><h2>Applications</h2><p>A 12V timer relay can be used in a wide range of applications where timing control is required in a low-voltage DC system. Some common applications include:</p><ul><li><strong>Automotive Systems</strong>: Timer relays are used in vehicles for functions such as delay-off headlights, intermittent window wipers, and automatic power window operation.</li><li><strong>Lighting Control</strong>: Timer relays can be used to control the timing of lighting systems, such as outdoor lighting, security lights, or interior lighting in homes, offices, and industrial settings.</li><li><strong>Irrigation Systems</strong>: Timer relays can be used in automated irrigation systems to control the timing and duration of watering cycles for gardens, lawns, and agricultural fields.</li><li><strong>HVAC Systems</strong>: Heating, ventilation, and air conditioning (HVAC) systems often incorporate timer relays for controlling the timing of various components, such as fans, compressors, and defrost cycles.</li><li><strong>Industrial Automation</strong>: Timer relays are used extensively in industrial automation processes, where precise timing is required for controlling equipment, machines, and processes.</li><li><strong>Control Panels</strong>: Timer relays are commonly used in control panels for various applications, including motor control, pump control, conveyor systems, and automated manufacturing processes.</li><li><strong>Security Systems</strong>: Timer relays can be utilised in security systems to control functions like alarm activation and deactivation, delay entry/exit mechanisms, or timed lighting to simulate occupancy.</li><li><strong>Aquariums and Terrariums</strong>: Timer relays are used to control lighting, heating, and filtration systems in aquatic and reptile habitats, providing scheduled day-night cycles and maintaining optimal conditions.</li></ul>

On Delay Timer Relays | Timer Relays |RS

<p>An On Delay Timer Relay is an electrical device used to introduce a time delay before energizing or de-energizing a circuit. It is commonly used in various industrial and automation applications where timing control is required.</p><h2>How does an On Delay Timer Relay Work?</h2><p>The purpose of an On Delay Timer Relay is to provide a delay between the input signal and the output action. When the input signal is received or a circuit is energized, the timer relay starts its timing cycle. After the pre-set time period elapses, the relay contacts change state, either closing or opening the circuit, depending on the configuration.</p><p>The time delay provided by the relay can be adjusted based on the specific requirements of the application. The delay can range from a fraction of a second to several hours, depending on the timer relays design and capabilities. Some timer relays allow for precise adjustment of the delay time, while others have fixed time increments.</p><h2>Applications of On Delay Timer Relays</h2><p>On Delay Timer Relays are used in various applications, such as motor control, lighting control, sequential control circuits, HVAC systems, and process automation. They can be employed to prevent immediate equipment start-up or to introduce a delay between different stages of a process.</p><p>RS offer a selection of on delay timer relays from leading suppliers, for all of your requirements based on the desired functionality for a particular application.</p>
