Dayton 24EN78 Time Delay Relay Octal Interval 240V AC 10A 8 Pin
An octal time-delay relay providing a single interval function adjustable from 1.8 seconds to 3 minutes for 240V AC circuits up to 10 A
- Adjustable timing from 1.8 seconds to 3 minutes via potentiometer
- DPDT contacts switch 10 A at 240 V AC or 30 V DC
- Octal 8-pin plug-in base for quick socket installation
- IP20 enclosed housing protects internal components
- Single interval-on delay function simplifies control logic
Relay Overview
The Dayton 24EN78 is a single-function time delay relay built for interval-on timing in 240V AC control circuits. It plugs into a standard octal socket and carries a 10 ampere DPDT contact set rated for both 240V AC and 30V DC loads. The unit is enclosed to IP20 and installs with a simple plug-in mount.
Suitability
This relay suits panels that need one adjustable interval timer between 1.8 seconds and 3 minutes driven by a potentiometer. It is not for applications requiring multiple timing functions, on-delay or off-delay modes, or coil voltages other than 240V AC. Buyers needing DIN-rail mount or different pin counts should look elsewhere.
Timing Range
The adjustable interval spans 1.8 seconds to 3 minutes, set by a front potentiometer, and this range decides whether the relay fits the process cycle. The 10 ampere DPDT contacts switch the load directly at 240V AC or 30V DC. Verify the required delay window against these limits before installing.

Questions about this item
How often will the internal contacts need replacement when switching 10 A loads?
The relay is rated for 10 A at 240 V AC and 10 A at 30 V DC; contact life depends on load type and switching frequency, so plan inspection intervals based on your actual duty cycle.
What stops continuous operation first — coil heating or contact temperature rise?
The 240 V AC coil and 10 A contacts share the same IP20 enclosed housing; sustained load current typically raises contact temperature before coil heating becomes the limiting factor.
Does the relay produce audible clicking or noticeable warmth when powered 24/7?
An electromechanical relay clicks once per interval cycle and the coil dissipates heat continuously; the IP20 enclosure will feel warm to the touch during all-day operation.
