Overview

Relays are widely used in electrical applications where one circuit is to be energized or turned "on" by the presence of a voltage, provided by another circuit. An example of this is when an automotive radio sends out a triggering voltage to turn on an external amplifier or activate a motorized antenna. Anywhere a switch can go in a circuit, a relay can replace it, (as long as there is a triggering voltage available to activate it).

The "switch" in a relay is more often called a solenoid. A solenoids is like a piston that pushes outward when energized with electricity. This push mechanically trips the switch in the relay, completing circuit and allowing the switched voltage output.

A relay can be triggered with an electrical pulse as small as 150 milliamps. The switched output can be as high as 20 amps.

Connections
The terminals of a relay are defined as follows:
  • 30 is the common or input voltage (or ground) to be switched.
  • 87a is the normally closed connection (can be used as a switched voltage output when the relay is at rest). (This terminal offers no voltage when the relay is energized.)
  • 87 is the normally open connection (switched voltage output when the relay is energized).
  • 85 is connected to the ground of the triggering voltage.
  • 86 is connected to the positive 12V of the triggering voltage.

Note: in many cases, the connection of pins 85 and 86 can be interchangeable, but NOT if there is a diode wired across the coil.

Below are several common examples of how relays are commonly used:
