Guide to Electrical Relays

Purchase electrical relays online


Electric relays are essentially electrical amplifiers with the ability to control an output circuit of greater voltage than the input circuit. Electrical relay manufacturers provide electrical relays for a variety of industrial applications. Voltage relays are available for many uses, including:

1. Time delay electrical relay

2. Overload protection relay

3. Solid state contactor relays for machinery requiring frequent on/off cycles

General purpose industrial relays are available in solid state, card, and ice cube relay designs, and are manufactured to handle varying amp levels. When searching online for electrical relay suppliers, know your options for purchasing new electric relays. If you're looking for replacement relays or to stock up on relays you currently use, it's helpful to know the part number and manufacturer you're looking for if you don't know the exact specifications of your relay. Even if they don't have the same product in stock, electrical relay manufacturers will be able to direct you to a sufficient substitute.


Action Steps

The best contacts and resources to help you get it done

Purchase solid state industrial relays Solid state voltage relays are non-contact relays utilizing semiconductors. They are useful in applications that require high-frequency and high-speed operations such as electric heaters and small electric motors.

I recommend:  Industrial relay provider Omron offers a selection of solid state relays. Browse their heater control, three-phase motors and socket style solid state relays.

Program your electronics with a timer delay relay Timer relays are useful when you want an electrical operation to start after a time delay. Timer relays incorporate mechanical clockwork to allow time delay lengths from fractions of seconds to multiple hours. Specify the delay period on the timer itself and alter it if your needs change.

I recommend:  Shop the online catalog of AutomationDirect for time delay electrical relays from multiple manufacturers. They also sell general purpose electrical relays, and all relays include LED indicators for simplified troubleshooting.

Buy specialty relays for non-standard electrical applications If you're looking for electrical relays to use in aerospace applications or in extreme temperatures, standard Internet searches for electric relay parts may not be fruitful. However, there are electrical relay manufacturers out there who provide relays for specialty applications. Look for a provider specializing in relays for military purposes, or one that supplies ultraminiature parts.

I recommend:  Teledyne Relays provides electrical relays for a wide variety of applications, including commercial aviation, space and heating and lighting. Use their search tool to enter the specifications of the relay you're looking for and find the product in their inventory that fulfills your needs.

Tips & Tactics

Helpful advice for making the most of this Guide
  • Purchase a relay tester to test the pickup level, time and coordination of ground-fault circuits. One relay tester can often monitor and test multiple electric relays.
