Time relays control when an output switches ON or OFF relative to an input signal or power event. The category covers several distinct timing functions, each suited to different control tasks:

On-delay (DOE): Output activates after a set time following energization. Used for motor start sequencing, conveyor delays, and compressor unloaded starts.
Off-delay (DODE): Output stays active for a set period after power is removed. Common in fan run-on applications and brake release circuits.
One-shot / pulse: Produces a single timed output pulse per trigger. Used in dosing, welding, and alarm suppression.
Repeat cycle (cyclic): Continuously alternates ON/OFF at set intervals. Typical for pump alternation, lubrication cycles, and signal lamps.
Star-delta timer: Dedicated sequencing for Y/Δ motor starters; controls winding transition timing.
Multifunction: Mode selected via DIP switch or rotary selector — one unit covers multiple timing functions, reducing panel inventory.

Mounting options include standard 17.5 mm or 22.5 mm DIN rail modules and plug-in socket types (8-pin or 11-pin octal base).

Key technical selection criteria

Timing mode: Match to the control requirement — on-delay, off-delay, cyclic, or one-shot
Timing range: Select a range that covers your required setpoint with reasonable resolution (e.g., 1–10 s, 0.1–10 min)
Supply voltage: 24 VDC for modern PLC panels; 110/230 VAC for legacy systems; multi-voltage models simplify stocking
Output contact rating: Typically 8–10 A at 250 VAC resistive; derate for inductive loads (contactors, solenoids)
Reset method: Power-off reset is standard; some applications require external signal reset
Mounting style: DIN rail for new panel builds; plug-in socket for direct replacement of existing relay bases

Comparison overview

Type	Typical use	Output active when
On-delay	Motor sequencing, conveyor start	After set time from energization
Off-delay	Fan run-on, brake release	Immediately; drops after set time from de-energization
One-shot	Dosing, welding, alarms	Fixed pulse duration per trigger
Repeat cycle	Pump cycles, lubrication	Alternating ON/OFF continuously
Multifunction	General panel use	Configurable via DIP switch or selector

What is the difference between on-delay and off-delay time relays?

On-delay activates the output after a set time following energization. Off-delay keeps the output active for a set time after power is removed — used for fan run-on or brake release.

Can a multifunction timer replace separate on-delay and off-delay units?

Yes. Multifunction timers use a DIP switch or rotary selector to set the timing mode, so one model covers multiple functions and reduces the number of different SKUs in a panel build.

What timing range is typically needed for a star-delta motor starter?

Most star-delta applications use a transition time of 3–30 seconds. A range of 5–15 seconds covers the majority of standard industrial motors.

Which supply voltage should I select for a time relay?

Use 24 VDC for PLC-based control panels and 230 VAC for legacy systems. Multi-voltage models (24–240 VAC/DC) are a practical choice when stocking for mixed installations.
