WebIn other relays, various mechanical devices have been used, including dash pots, bellows, and escapement mechanisms. The terminology for expressing the shape of the curve of operating time versus the actuating quantity has also been affected by developments throughout the years. Originally, only the terms "definite time" and "inverse time" were ... WebA signal at both the maximum switching voltage and the maximum switch current will generally exceed the power rating of the relay. For example, a relay with a 60W power rating, may have a maximum switching voltage of 250V and a maximum switch current of 2A. A 250V, 2A signal has a power of 500W, which exceeds the power rating of the relay by ...
