Time Delay Relays are electrical machines commonly used in control and automation systems to cause an event to happen after a preset amount of time. A time delay relay is analogous to a timer. It can be used to control a circuit for a predetermined length of time before it turns off automatically. For instance, it’s necessary to keep a motor on for a certain amount of time to reach steady state before performing certain operations.

Among time delay relays, 7012PKX is used widely. It is a micro-processor-based time-delay relay designed to provide accurate timing for a wide variety of applications. The 7012PKX is a single-channel device, 8-digit LED display and output on-delay and off-delay functions, as well as pulse and interval controls. It has an adjustable timer range 0.1 second to 999.9 minutes, which can be set up the timer range by pressing the digital keys.

The 7012PKX application field includes security and surveillance, electronic machines, packaging and production control, sprinkler systems, motors, HVAC/R equipment and solenoid valves. As for working principle, 7012PKX time-delay relay works related to the internal timer. The internal timer can be established by a variety of methods. These include digital input, digital output, or selectable external input signals. When the relay is triggered, the timer clock starts and the internal timer begins counting down. After the preset time elapses, the internal timer will trigger the desired output.

The 7012PKX features excellent accuracy, internal diagnostics that detect power-on, introduction of failure and output closing. Moreover, the anti-vibration characteristic of the relay also means that it can be used in applications with a considerable level of vibration. This time-delay relay is also self-protected and easy to analyze and maintain.

7012PKX time-delay relay is an efficient and reliable device for control and automation systems. It comes with versatile features, excellent accuracy and strong anti-vibration characteristic that provide precise control. The diversity of application fields and wide timer range makes it suitable for a wide range of applications.
