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

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
