Time Delay Relays

Time delay relays are electrical relays whose window of operation is determined by a timing element. The timing element is most commonly either an electromechanical timer consisting of a motor winding and spring-loaded contacts, or a solid state sequence timer. While these devices were once entirely electromechanical in nature, the increasingly widespread use of the microprocessor has lead to their most common current form being a solid state digital device, interlocked with an SSR or mechanical output.The purpose of a time delay relay is to provide a delay under certain conditions. For instance, in an HVAC application, the motor may need to be kept running for a certain period of time in order to properly heat and cool the environment. A time delay relay can be used to delay the start of the motor, or to keep the motor running for an additional set amount of time. It can also be used to provide a circuit with a safety mechanism, in which the delay prevents an overload of equipment that may not have been designed to handle a sudden surge.The H2C-F-AC24-B is a time delay relay designed for use in a wide variety of applications, ranging from HVAC control to industrial automation and process control. This relay uses an electromechanical timer to provide an adjustable timing range. It can be programmed to a desired setting from 0.01 to 10 minutes in increments of 0.01. The H2C-F-AC24-B offers two types of timing functions - power on delay and power off delay. In power on delay, a preset time period of 0.01 to 10 minutes elapses after the power is applied before the relay contact operates. In power off delay, the contact operates instantly when the power is applied, but a preset time period, again from 0.01 to 10 minutes, elapses after the power is removed before the relay contact returns to its start position.The H2C-F-AC24-B has two built in LEDs indicating its operating status, which makes it easy to monitor. It also features an energized reset, which enables the delay to be reset at any time, while the power is still on. This is useful for resetting the device from an outside switch or from a specific external event. The H2C-F-AC24-B is a useful device for controlling different types of loads, and offers a consistent, reliable timing range that is adjustable to meet the specific needs of the application. Whether used for HVAC control, industrial automation, or any other type of application, the H2C-F-AC24-B time delay relay can be a valuable addition to a circuit.
