Time Delay Relays

Time Delay Relays (TDR) are a type of relay that is constructed with an onboard timer. These relays are commonly used for the purpose of control and timing of various industrial and commercial applications, such as production line automation, automotive component testing, and monitoring of energy consumption. The purpose of a TDR is to enable a device to perform a task at a given time, rather than immediately, such as turning off a light several seconds after the user has exited the room.

KRDB31120S: Application Field and Working Principle

The KRDB31120S Time Delay Relay is a versatile product manufactured by Koninic. It is used mostly in applications that require precise control over the sequencing and timing of related stages of an event. The KRDB31120S is mainly used in applications such as directional control, starting and stopping of motors, hot gas bypass controls, and pulse stretching applications.

The KRDB31120S Time Delay Relay consists of a number of timers, each of which is activated by the closing of a switch. All timers can be set to work simultaneously or independently. The KRDB31120S also offers a wide range of timing ranges from 0.1 seconds to 10 minutes. The KRDB31120S Time Delay Relay is equipped with two time scales that can be used to program the timer. The first time scale is the main time, which is used to delay the off-switch time for the first timer and the second time scale is used to set the time for the second, third, and fourth timers.

The KRDB31120S Time Delay Relay is constructed with a relay contact that can perform the switching function with a maximum switching current of 10A and a voltage of 250VAC. The relay contact is also rated for an enclosure rating of IP40, which makes it suitable for use in a wide range of industrial and commercial environments.

The working principle of the KRDB31120S Time Delay Relay is quite simple. When the switch is closed, the timer starts and when the timer reaches the desired time, it switches the power off, thus stopping the device or process that was being timed. The timing process of the KRDB31120S Time Delay Relay is regulated by an integrated 555 timer IC.

The KRDB31120S Time Delay Relay is a versatile and reliable product for applications that require precise control over the sequencing and timing of related stages of an event. This product is constructed with a durable casing and is rated for an enclosure rating of IP40, which makes it suitable for use in a wide range of industrial and commercial environments. The KRDB31120S Time Delay Relay is a reliable and accurate device that can perform a wide range of timing functions in a variety of different applications.
