More Information on Solid State Relays (SSR)...

What is a Solid State Relay?

An SSR, or solid state relay, is an electronic switch that contains no moving parts and that has the same use as an electromechanical relay.In an SSR a small control signal controls a larger load current or voltage.

Solid state relays consist of:

A sensor which responds to a control signal

A solid state electronic switching device

A coupling mechanism

The switching device is used in order to switch power to the load circuitry.The coupling mechanism enables the control signal to activate the switch without any moving parts.

Types of Solid State Relays

Future Electronics offers more than 1,000 Solid State Relays, one of the most comprehensive inventory ranges of SSRs in the industry.Our parametric filters refine your search results by Contact Current, Contact Arrangement, Output Voltage, Control Voltage, On-State Resistance and Isolation Voltage.We have a full selection of Single and Dual Channel solid state relays in SPST, SPDT, DPST and DPDT combinations, with current ratings all the way from 1.1 mA to 500 A. The most common sizes for Maximum Isolation Voltage are 1500 V, 2500 V, 3750 V, 4000 V and 5000 V.

Applications for Solid State Relays:

Solid state relays are ideal for repetitive applications due to the absence of moving parts.Some applications for solid state relays are:



Professional food equipment

Theatrical lighting

Industrial machinery

Control panels

Elevators and lifts

I/O interfaces

Choosing the Right Solid State Relay:

When you are looking for the right solid state relays, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Maximum Contact Current (1.1 mA to 500 A), Maximum Isolation Voltage (200 V, 1500 V, 2500 V, 3750 V, 4000 V, 5000 V,…) and Output Voltage (up to 800 V) to name a few.The parametric filters on our website can help refine your search results depending on the required specifications.

Solid State Relays in Production Ready Packaging or R&D Quantities

If the quantity you want is significantly less than a full reel quantity, we offer many of our Solid State Relay products on special mini-reels, giving you the convenience of being production ready, without any unneeded surplus.

Future Electronics also offers its clients a unique bonded inventory program designed to eliminate potential problems that may arise from an unpredictable supply of products that could contain raw metals and products with erratic or long lead times.Talk with your nearest Future Electronics branch and find out more on how you can avoid possible shortages.
