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 ...

The CPC1390G is a 4-pin, single pole and normally open solid state relay that has input to output isolation of 5000 Vrms. It has a blocking voltage of 400 Vp and does not generate EMI or RFI ...

My July 3 column covered the theory and operation of potential relays. This article covers potential relay ratings and specifications along with systematic troubleshooting. Here is an example of a ...

Last month we examined the operation and application of the potential starting relay. This month we will cover voltage specifications of the potential relay. Compressors may have one of three voltage ...

Pickering Electronics, has announced its first high voltage surface mount reed relays known as the Series 219. Available in multiple package types (of the same size, but with differing pin positions), ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
