Time Delay Relays play an important role in industrial and manufacturing applications by providing timed outputs to parallel systems, allowing them to move or activate components or machinery in sync. The KRDR420A3 is a type of Time Delay Relay with specific features that are tailored to fit various applications.The KRDR420A3 combines the control function of a relay and time delay in one unit. When the control switch is turned on, the KRDR420A3\'s timer starts working, and its output will be active after the preset delay time has elapsed. This function is useful in certain large machines when it must be operated in a sequential fashion, i.e. one component activated after the other one.The KRDR420A3 also has a time-out function: after the programmed time, the output will repeatedly switch on and off at a given interval. This feature can be used for processes such as sending multiple signals automatically or providing a delayed off-pause as part of a sequence operation.An adjustable dial is provided to determine the amount of delay. It has a maximum delay time of 40 minutes with a precision of one second which allows an exact adjustment of the time. The timer is powered by an AC supply and can be controlled by hand or normally open/normally closed contacts.The KRDR420A3 offers a wide range of applications, where the time delay is essential. These include machine tool programming, machine startup, transfer of materials, production line control, etc. It is also suitable for use in water pumps, conveyors, fans, process control and electric door control systems.The KRDR420A3 is built with a durable, high-quality plastic casing with a dust- and moisture-resistant contour that prevents dust and other particles from getting inside the relay. It also has a safety circuitry that protects against shorting and overloads.The KRDR420A3 is designed to be easy to install and to provide reliable performance in harsh industrial environments. It is fully compliant with world safety standards and certified for use in most countries. The KRDR420A3 is a solid choice for industrial applications, offering reliability and accuracy.
