Encapsulated Timer Relay for 24V AC Circuits

This Dayton 5WML4 relay provides a single off-delay timing function in a fully encapsulated housing. It is intended for control panels and automation systems that require a solid-state output switching up to one ampere at 24 volts AC. The five-pin screw-terminal base mounts directly on a flat surface for straightforward installation.

Consistent Off-Delay Operation Under Continuous Use

The solid-state output eliminates mechanical contact wear, so timing accuracy remains stable over extended duty cycles. Encapsulation protects the internal circuitry from dust and moisture, allowing the relay to maintain its 0.05-second minimum and 1-second maximum delay settings without degradation from environmental exposure or repeated switching events.

1 A at 24V AC Contact Rating Determines

The relay switches a maximum of one ampere at 24 volts AC and carries no DC rating, so it cannot be used in higher-current or DC control circuits. Builders needing greater current capacity, additional delay functions, or a different coil voltage must select an alternative timing relay.

Questions about this item

How much heat or power does the 5WML4 draw when it runs continuously on 24 V AC?

The relay draws only the coil current needed for 24 V AC operation; its solid-state output switches up to 1 A at 24 V AC with no moving parts, so heat stays low during all-day use.

What wiring or mounting hardware must I already have to install this square-base relay?

You need a 24 V AC supply, screw-terminal wiring for the five pins, and a flat surface for the 2 in deep, 0.79 in high encapsulated body.

Will the 0.05–1 sec off-delay work reliably with older electromechanical contactors in the same panel?

Yes, the solid-state SPST-NO output provides bounce-free switching that is compatible with legacy contactors driven from the same 24 V AC source.
