This Product Selection Guide contains information to help select products in the Time Delay Relays category on DigiKey.com
Time Delay Relays are electromechanical devices that turn a large load on or off through the use of a smaller control signal. These devices have a built-in time delay to control triggering of the relay. The functions are interval, off-delay, on-delay, one-shot, programmable (multi-function), repeat cycle, twin timer, signal on-off-delay, and star/delta controller.
SelectionCharacteristics
Mounting Type: Indicates how the device is attached.
Relay Type: Describes the internal construction of the relay or method of how it funtions.
Function: Describes how the item behaves when given a trigger.
Circuit: Describes device function in terms of a number of poles and throws, as is common for mechanical switches.
Delay Time: Describes a fixed or adjustable period of time after a monitored circuit exceeds some defined threshold that a device will wait before actuating its output.
Contact Rating @ Voltage: The amount of current that a relay’s contacts are rated to interrupt when switching a resistive load at the rated voltage.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Termination Style: Describes the shape or standard configuration of a device’s electrical connection(s).
Timing Adjustment Method: Describes the user interface for configuration of the device.
Timing Initiate Method: The trigger the device uses to cause the timing function to start.
