Timing relays are devices used in electrical systems to control the timing of various operations. They are designed to provide specific time delays in activating or deactivating electrical circuits. Timing relays are commonly used in industrial automation, control systems, and process industries where precise timing is critical.
Timing relays consist of an electromechanical or electronic control mechanism and a set of contacts. The control mechanism monitors the input signal and triggers the relay's contacts after a specified time delay. The delay can be set manually or programmed through electronic controls.

Time delay relays are electronic devices that introduce a time delay in the operation of electrical circuits. They are commonly used in industrial automation, control systems, and various applications where timed control or sequencing of events is required. Time delay relays provide a delay between the application or removal of a control signal and the activation or deactivation of the connected load. They enable precise timing control, automation of processes, and protection against undesirable conditions by introducing delays in electrical circuits. A full line of industry standard time delay relays are manufactured under the "Signaline" trade name.

A multifunction relay refers to a type of relay that performs multiple functions or offers multiple operating modes in a single device. Relays are electromechanical or electronic devices used to control electrical circuits by switching them on or off in response to an input signal.

Anti-short-cycle timer prevents premature cycling of compressors in refrigeration, air conditioning and heat pumps, thereby reducing nuisance tripping of fuse or circuit breaker. When power is applied (i.e. thermostat closes), the load energizes. Removal of power begins the “lockout” and the time delay begins (i.e. locking out the compressor). The load is energized after the time delay expires. S1 option provides a 1-second delay before the load is energized. Delay On Make option delays the initial load output for up to 5 minutes.
True Off Delay
Application of the supply voltage energizes the output relay. The timing period begins upon removal of the supply voltage. At the conclusion of the timing period, the output relay is de-energized. Reapplication of input voltage before the delay expires resets the time period. Instantaneous Contact option: Application of supply voltage for a minimum of 100 milliseconds initiates time out. Instantaneous contact and timed contacts transfer. Upon removal of supply voltage, instantaneous contact drops out, and timed contacts remain closed for duration of selected time (off-delay) then drop out. Reapplication of power starts the cycle.
Interval, Interval Delay
An interval on timer is a type of timer or relay that operates in an intermittent or cyclical manner with specified intervals of operation and rest. It is commonly used in applications where periodic control or timing functions are required. When power is applied to the input voltage terminals, the load is energized immediately and the time delay cycle starts. At the end of the delay period, the timer transfers back to its pre-power position. Removal and re-application of input voltage resets the timer. Delayed Interval: Application of power to the input terminals starts the “Off” time. When this time is complete, the load energizes for the “On” time. At the end of the “On” time, the load de-energizes and remains in this state until the input power is removed and reapplied to start a new timing cycle. Both time periods can be individually adjusted.
The term “Single Shot” signifies a single pulse output of some duration.
Single Shot on Make: Power must be applied to the input voltage terminals continuously. Upon closure of a Normally Open (N.O.) external initiate switch, the load is instantaneously energized and the time delay cycle starts. Maintained closure or actuation of the external initiate switch during the delay cycle will not affect the time delay period. When the delay period expires, the timer will reset to its original position and is ready for another cycle.
Single Shot on Break: Power must be applied to the input voltage terminals continuously. Upon closing and opening an external initiate switch, the load is instantaneously energized and the time delay cycle starts. When the delay period expires, the timer will reset to its original position and is ready for another cycle.

A repeat cycle timing relay is an electrical device used to control the on/off operation of a load or circuit with repeated cycles. It provides a repeating or cyclical timing function, where the on-time and off-time durations can be independently set or adjusted.
Application of power to the input voltage terminals starts the “Off” delay cycle. At the end of the “Off” delay period, the load is energized and the “On” delay starts. At the end of the “On” cycle, the load is de-energized, the timer returns to the “Off” cycle and the cycling is repeated as long as input voltage is applied. Removal of input voltage will reset the timer to its pre-power condition.
Off Delay, Delay on Release, Delay on De-Energization
A delay on break timing relay is an electrical device used to introduce a delay in the de-energization or turning off of a load or circuit after a control signal is removed. It provides a specific time delay before the load or circuit is de-energized, allowing for additional operation or control during the delay period.
Power is continuously applied to the input terminals of the timer. Upon closure of a Normally Open (N.O.) external initiate switch, the load transfers immediately and remains transferred as long as the external initiate switch is closed. Commencement of the time delay is deferred by maintaining closure of the external initiate switch. Opening the initiate switch starts the time delay. At the end of the delay period, the load de-energizes and the timer is ready for another cycle. Delay time may be reset to beginning, prior to the end of the delay period, by momentarily reclosing (pulsing) the initiate switch.
On Delay, Delay on Operate, Delay on Energization
A delay on make timing relay is an electrical device used to introduce a delay in the energization or turning on of a load or circuit after a control signal is applied. It provides a specific time delay before the load or circuit is energized, allowing for additional control or operation during the delay period.
