Interrupting low-voltage circuits handled by general-purpose relays is fairly straightforward. However, as circuit voltage increases, so too does the difficulty. Interrupting a kilovolt circuit with ...

1. The well-established relay-driving circuit uses an optocoupler to isolate the grounds and noise coupling between the low-voltage digital-control signal circuit (left) and the relay as load (right).

Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

The Micro ICCS relay has one analogue plus three digital inputs as well as two power outputs (high-sides) or one relay output and one signal output up to 2 watts. The use of the high-side-drivers ...

Even though the function of single phase and three phase relays are quite similar, their applications can vary significantly. This is primarily due to the characteristics of three phase power circuits ...

The PSR-MXF multifunctional safety relay is the newest addition to the Phoenix Contact PSR safety relay line. This relay can help small and medium machine builders reduce cost and save space. The ...
