Rated for 1750W of DC power or 1750 VA of AC power No need to be worried about a voltage spike For DC applications, you can switch a circuit of up to 30V and 5A For AC applications, you can switch up to 12A or 277V AC If you need to switch power to a device without the hassle of a big expensive relay, the Phidgets VINT Relay Module is here as a quick an easy option. Rated for 1750W of DC power or 1750 VA of AC power, this mechanical relay is suitable for a wide range of applications. Relays by nature are isolated, so you don't have to worry about a voltage spike on the load side of the relay damaging the control side. If mechanical relays are too slow or noisy for your purposes, have a look at the "Other Relays" tab and chose a solid-state relay (SSR) board. AC or DC Switching For DC applications, you can switch a circuit of up to 30V and 5A. For AC applications, you can switch up to 12A or 277V AC, as long as the total power doesn't exceed 1750 VA.
