Small rectangular relay with octal base and potentiometer dial

Dayton

Dayton 24EN72 Time Delay Relay Octal Interval 24V AC/DC 10A DPDT

SKU CH-9A3H-QMQPY

An octal-base interval timer relay switches loads up to 10 A at 240 V AC or 30 V DC with a 3 s to 5 min adjustable delay

  • Adjustable timing from 3 seconds to 5 minutes with potentiometer control
  • Octal 8-pin plug-in base enables quick socket installation
  • DPDT contacts switch 10 A at 240 V AC or 30 V DC
  • Operates on 24 V AC or DC coil voltage for flexible power
  • IP20 enclosed housing protects internal components in industrial environments

Application Focus

The Dayton 24EN72 is a single-function time delay relay designed for industrial control circuits that require a precise interval-on delay. It suits panel builders, maintenance technicians and OEMs who need reliable timing in motor starters, lighting panels or process equipment. The octal plug-in format allows quick installation in standard sockets without rewiring.

Upgrade Path

This relay replaces older fixed-timer or multi-function modules when only a simple interval-on sequence is needed. The jump is worthwhile when a potentiometer-adjusted range of 3 sec to 5 min covers the application and when a single DPDT contact set rated at 10 A simplifies the bill of materials. It also fits panels where an IP20 enclosed housing meets safety requirements.

Build Integration

The unit plugs into an 8-pin octal socket and operates on 24 V AC/DC coil voltage, drawing power from common control transformers. Its DPDT contacts switch up to 10 A at 240 V AC or 30 V DC, freeing the designer from adding an interposing contactor for moderate loads. The enclosed construction and IP20 rating allow mounting in standard enclosures without additional guarding.

Questions about this item

What octal socket and 24 V AC/DC supply does the 24EN72 require?

The relay plugs into an 8-pin octal socket and operates on 24 V AC or DC.

How is the interval-on delay set, and what common step is missed?

Turn the potentiometer between 3 sec and 5 min; the step often missed is applying power after setting the dial.

When should the DPDT contacts rated 10 A at 240 V AC be replaced?

Replace the relay when contacts no longer switch the rated 10 A load reliably.
