What is a relay?• Electrically operated switches that allow one electrical circuit to control one or more other

circuits by opening and closing its contacts in response to energizing or de-energizing its coil

• Relays are either electromechanical (EMR) or solid-state (SSR)

• General purpose relays are electromechanical switches that are usually operated by a magnetic coil and operate with AC or DC at common voltages such as 12 V, 24 V, 48 V, 120 V and 230 V, and can control currents ranging from 2 A to 30 A

• A relay involves two circuits: the energizing circuit and the contact circuit. The coil is on the energizing side. The relay contacts are on the contact side

• A timing relay is a simple form of time-based control, allowing the user to open or close the contacts based on a specified timing function


Why choose Eaton relays?Eaton has a robust offering of EMR and SSR relays to fit a wide range of application ranges and needs

General Purpose Timing

Terminal Block Solid State Alternating


Relay 101: basic functions and terminology• Frame – Contains and supports the

parts of the relay

• Coil – Wire is wound around a metal core, and causes an electromagnetic field when energized with a current

• Armature – The moving part of the relay that opens and closes the contacts, using a spring to return to the original position

• Contacts – The conducting part of the switch that makes (closes) or breaks (opens) a circuit

Relay in rest state Relay in engaged state

Relays involve two circuits: the energizing circuit and the contact circuitWhen the coil is energized, the electromagnetic field attracts a ferrous plate on the armature


Relay 101: basic functions and terminology• Contacts – come in a number of configurations, depending on the number of breaks, poles,

and throws in the relay

• Pole – the number of completely isolated circuits that a relay can pass through a switch

• Break – the number of separate places or contacts that a switch uses to open or close a single circuit

• Throw – the number of closed contact positions per pole that are available on a switch

• Examples:

• SPDT – can carry current through one circuit and can control two independent circuits

• DPDT – can carry current through two circuits and can control two independent circuits
