What is the NO SPST normally open relay? The NO Normally-Open SPST (Single Pole Single Throw) relay has an opened circuit state when no current is applied to its coil so basically it disconnects the ...

What is the normally closed SPST relay? The NC Normally-Closed SPST (Single Polse Single Throw) relay has an initial closed circuit state when no current is applied to its internal coil therefore it ...

Some SPST relays can handle upwards of 70 amps, making them perfect for high-current applications, like oversized cooling fans. But they aren't without limitations.

The MM1205 offers flexible and versatile configuration capabilities: 6x SPST, 2x SP3T, 3x SP2T, and 1x SP6T. The MM1205 6x SPST relay represents the culmination of several important industry firsts: ...

Two dry-reed relays were compared in the first study. The first device was a single-pole single-throw (SPST) relay and the second a four-pole single-throw (FPST) relay.

There are sometimes small complicating factors. One is that on simple 4-pin SPST relays without internal diodes, current can flow through them in either direction, so you may find that they’re ...

This MOSFET-output optocoupler provides an SPST relay function and targets the high voltages of electric-vehicle battery packs.

Many of the electromechanical relays used in automotive applications are termed ISO relays.

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs. The Click C0-04TRS-10 ($54.00) is a ...
