Delay Relay Information
Show all time delay relay manufacturers
Time Delay Relay Information Time delay relays and solid state timers use solid state electronics to provide time delays. They may have displays, tanks or other means of operating the interface. They may also have electromechanical or solid state outputs.
The number of time ranges on relays and timers is single or multiple:
Individual time ranges can be fixed or programmable.
Multiple time ranges can be programmed for multiple ranges.
Minimum and maximum time settings must also be specified. Some relays and timers have field selectable time ranges.
Delay relays and solid state timers can have many timer functions or modes of operation, including:
turn-on delay
off delay
Shooting and Spacing
type
ON-delay timers and OFF-delay timers are two common types of delay relays and solid-state timers.
Turn on delay timer
This type of timer can also be called:
delayed production
Delay operation
Operation delay
Pre-Purge Delay
Power up delay
The time delay starts after power up. At the end of the time delay, the contacts open or close. If the contact is normally open (NO), the load is energized at the end of the delay. If the contacts are normally closed (NC), the load is de-energized after a delay. Power loss resets the time delay and output.
Turn off delay timer
This type of timer is sometimes called:
delayed rest
release delay
delayed release
Postpurge delay
Power-off delay
Delay Relay Information
The timer contacts open or close immediately after a power failure. A preset time delay must elapse before the contacts return to their normal positions and the load is de-energized.
Power must be applied before and during the timing. Reclosing the control switch during the timing resets the time delay. Most reset on power down.
one-click timer
One-shot timers are time delay relays and solid state timers, also known as:
one-shot relay
Single shot
single shot interval
single pulse
Latching Relay
lock delay
Latch Delay on Power Down
The contacts change position immediately upon power-up and remain in the changed position for a preset time delay. After the delay, the contacts return to their normal positions. Power must be applied before and during the timing. A reset occurs when the time delay is complete and the control switch is opened.
interval timer
Interval timers are time delay relays and solid state timers, also known as:
in the interval
pulse shaping
Bypass timing
interval delay
Instantaneous Transmission Delay Power On
The time delay starts from power up. The output is energized during the delay, de-energized at the end of the delay, and remains de-energized until de-energized.
Recycle timer
This type of relay is also known as:
work cycle
cycle
repeat cycle
Delay operation and release
On/Off double delay
Flasher
Dual Delay Power On
The timing function begins when the control switch is closed. The load is periodically turned on and off alternately until power is removed. A power loss resets the time delay.
The time indicator records and displays the elapsed time, but does not perform an output function. Some timers can be programmed to function as counters as well as timekeeping. Delay relays and solid-state timers are either single-function devices or multi-function devices.

Output specifications to consider when selecting time delay relays and solid state timers include switch type, number of contacts, contact configuration, and pole and throw specifications.
Mounting hardware and power supply also need to be specified. Operating temperature is an important environmental parameter to consider when selecting time delay relays and solid state timers.
