Dayton

Dayton 1EHA1 Plug-In Relay Octal 12A 11 Pin 12V DC 3PDT

SKU CH-NET3-4RKHT

Octal-base plug-in relay with 11 pins, 12 V DC coil and 3PDT silver-alloy contacts rated 12 A at 240 V AC or 28 V DC

  • Handles 12 A loads on both AC and DC circuits
  • 11-pin octal base plugs straight into standard sockets
  • 12 V DC coil suits common control-voltage systems
  • 3PDT contact form switches three independent circuits at once
  • Hermetically sealed body resists dust and moisture ingress

Octal 11-Pin Relay for 12V DC Systems

The Dayton 1EHA1 is a plug-in general-purpose relay with an octal base and eleven pins. It switches loads up to twelve amperes on a three-pole double-throw contact arrangement. The coil operates at twelve volts DC, making it suitable for low-voltage control panels and machinery circuits.

Plug-In Mounting Frees Panel Space

The relay body measures 1.61 in deep, 2.1 in high and 1.44 in wide, fitting standard octal sockets without screws or brackets. Plug-in mounting allows quick replacement and keeps the enclosure interior clear for wiring. Silver-alloy contacts handle both AC and DC ratings without a separate indicator circuit.

Hermetic Seal Sustains Rating Under Load

A hermetically sealed case protects the contacts from dust and moisture during continuous operation. The contact rating holds at twelve amperes at 240 V AC or twenty-eight volts DC, and the motor ratings remain at one-third horsepower at 120 V AC and one-half horsepower at 240 V AC. No status indicator means the sealed assembly stays intact for the full duty cycle.

Questions about this item

What is the maximum current the contacts can switch continuously before overheating?

The relay is rated for 12 A continuous current at both 240 V AC and 28 V DC.

How much heat does the coil generate when energised for long periods?

The coil operates at 12 V DC; power draw is low, so heat rise inside the 1.61 in deep body is minimal.

Which socket or base must I already have to plug this relay in?

It requires an 11-pin octal socket that matches the 1.44 in wide plug-in footprint.
