SparkFun’s latest tutorial shows you how to work with relays. A relay is an electrically operated switch. In this case, they’re using it to switch a 120V AC outlet. The article carries the ...

Relays must be thoroughly tested during qualification stage, and there are a number of specifications that must be tested. Table 1 below shows some of the AC performance specifications. The coil ...

Conversely, when the reset coil is energized, the relay enters the reset-state. The two coils are never energized at the same time. If you wish to use a dual-coil relay, but the only driver you have ...

He realized that when the coils in the sensor were energized they were putting out about 7 volts AC, which should be more than enough to trigger a relay.

The G9TA range of power latching relays are designed for applications up to 60A (at 250Vac) maximum switching current. These G9TA relays feature 2mΩ contact resistance, 6kV impulse withstand voltage, ...

Rather than use a fixed-rail voltage source, it’s more efficient and flexible to utilize a current source so that performance remains consistent while supply rail and coil resistance ...
