abstract: What is a Solid State Relay?
Full Text: 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.
- 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.
In addition, we offer a unique bonded inventory program that eliminates potential problems arising from volatile market conditions like an unpredictable supply of products containing raw metals and parts with erratic or long lead times. Talk with your local Future Electronics team to learn more about how you can avoid possible shortages in the future today.
