Eaton TRL04 Multifunction Time Delay Relay
Multifunction time delay relay with four selectable functions, 24 to 240 V AC/DC coil voltage, 8 A SPDT contacts and 0.05 s minimum delay
- Four selectable delay functions suit varied timing tasks
- Wide 24 to 240 V AC/DC coil voltage fits many control circuits
- SPDT contacts rated 8 A at 250 V AC handle typical loads
- Adjustment via rotary DIP switch with 0.05 s minimum setting
- IP40 enclosure protects internal components in panel installations
Multifunction Time Delay Relay
The Eaton TRL04 is a multifunction time delay relay designed for control-panel and machinery applications. It provides four selectable delay functions in a single octal-base unit, suited for engineers and maintenance teams managing timing sequences in industrial equipment.
Octal Base with Screw-Clamp Terminals
The relay mounts in a standard octal socket and uses screw-clamp connections for secure wiring. An IP40 rating protects internal components against solid objects larger than 1 mm, making it appropriate for enclosed cabinet environments where dust ingress is a concern.
Four Functions Across 24 to 240 V AC/DC
The coil operates from 24 to 240 V AC/DC, covering common control-circuit voltages without separate models. Adjustable from 0.05 seconds via rotary DIP switch, the four modes include flasher pause first, on/off delay, power triggered and single shot leading edge voltage controlled, with an SPDT contact rated at 8 A / 250 V AC. Buyers who need more than four timing modes or a different contact arrangement should look elsewhere.

Questions about this item
What voltage range does the TRL04 accept on its coil?
The coil operates on 24 to 240V AC/DC, so it covers both low-voltage control circuits and standard mains supplies without needing a separate transformer.
What socket or base style is required to mount this relay?
It uses an octal base with screw-clamp terminals, so you need an 8-pin octal socket wired to the screw clamps for a secure panel or DIN-rail installation.
How do I select one of the four timing functions on the TRL04?
Rotate the rotary DIP switch on the face to the desired function — flasher pause first, on/off delay, power-triggered, or single-shot leading-edge voltage-controlled — then set the delay with the time knob.
