The PhidgetInterfaceKit 0/0/4 is a mechanical relay board designed for a wide range of switching applications.
It includes four SPDT mechanical relays capable of switching AC or DC loads, giving you control over high-power devices such as incandescent bulbs, fans, pumps, and more.
You can connect the PhidgetInterfaceKit 0/0/4 directly to your computer via USB or through a VINT Hub Phidget.
Note: This board is not suitable for switching signals. It takes at least 100mA of current to bridge the oxide layer that forms on the relay contacts, and most signals will not meet this requirement. If you need to switch signals, check out the Signal Relay Phidget or the PhidgetInterfaceKit 0/0/8.

*Note: Switching this relay at voltages higher than 30V will result in a reduced product lifespan.
Please Note: This relay cannot be switched at its maximum AC voltage and current at the same time. Ensure that total power of the load does not exceed the switching power for the relay. For example, you can switch this relay at 277V AC and 6.3A (1750VA), or at 145V AC and 12A (1750VA), but not at 277V and 12A (3324VA).The lifespan of the relays on this Phidget vary depending on how much current you're switching and whether it's AC or DC. The following graph illustrates the relationship between load current and relay lifespan:
The vertical axis is the lifespan of the relay (number of actuations) and the horizontal axis is load current in amps. As you can see, increasing load current from 5A to 10A can reduce relay life by more than half.

Use a USB cable if you want to connect this Phidget directly to your computer. We have a number of different lengths available, although the maximum length of a USB cable is 5 meters due to limitations in the timing protocol. For longer distances, we recommend that you use a Single Board Computer to control the Phidget remotely.
